public class Paragraph 
extends CompositeNode

Represents a paragraph of text.

Paragraph is a block-level node and can be a child of classes derived from Story or InlineStory.

Paragraph can contain any number of inline-level nodes and bookmarks.

The complete list of child nodes that can occur inside a paragraph consists of BookmarkStart, BookmarkEnd, FieldStart, FieldSeparator, FieldEnd, FormField, Comment, Footnote, Run, SpecialChar, Shape, GroupShape, SmartTag.

A valid paragraph in Microsoft Word always ends with a paragraph break character and a minimal valid paragraph consists just of a paragraph break. The Paragraph class automatically appends the appropriate paragraph break character at the end and this character is not part of the child nodes of the Paragraph, therefore a Paragraph can be empty.

Do not include the end of paragraph ControlChar.PARAGRAPH_BREAK or end of cell ControlChar.CELL characters inside the text of the paragraph as it might make the paragraph invalid when the document is opened in Microsoft Word.

Example:

Creates a simple document from scratch using the Aspose.Words object model.
// Create an "empty" document. Note that like in Microsoft Word, 
// the empty document has one section, body and one paragraph in it
Document doc = new Document();

// This truly makes the document empty. No sections (not possible in Microsoft Word)
doc.removeAllChildren();

// Create a new section node
// Note that the section has not yet been added to the document, 
// but we have to specify the parent document
Section section = new Section(doc);

// Append the section to the document
doc.appendChild(section);

// Lets set some properties for the section
section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
section.getPageSetup().setPaperSize(PaperSize.LETTER);

// The section that we created is empty, lets populate it. The section needs at least the Body node
Body body = new Body(doc);
section.appendChild(body);

// The body needs to have at least one paragraph
// Note that the paragraph has not yet been added to the document, 
// but we have to specify the parent document
// The parent document is needed so the paragraph can correctly work
// with styles and other document-wide information
Paragraph para = new Paragraph(doc);
body.appendChild(para);

// We can set some formatting for the paragraph
para.getParagraphFormat().setStyleName("Heading 1");
para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);

// So far we have one empty paragraph in the document
// The document is valid and can be saved, but lets add some text before saving
// Create a new run of text and add it to our paragraph
Run run = new Run(doc);
run.setText("Hello World!");
run.getFont().setColor(Color.RED);
para.appendChild(run);

// As a matter of interest, you can retrieve text of the whole document and
// see that \x000c is automatically appended. \x000c is the end of section character
System.out.println(doc.getText());

// Save the document
doc.save(getArtifactsDir() + "Section.CreateFromScratch.doc");

Constructor Detail

Paragraph

public Paragraph(DocumentBase doc)
Initializes a new instance of the Paragraph class.

When Paragraph is created, it belongs to the specified document, but is not yet part of the document and ParentNode is null.

To append Paragraph to the document use InsertAfter or InsertBefore on the story where you want the paragraph inserted.

Parameters:
doc - The owner document.

Example:

Creates a simple document from scratch using the Aspose.Words object model.
// Create an "empty" document. Note that like in Microsoft Word, 
// the empty document has one section, body and one paragraph in it
Document doc = new Document();

// This truly makes the document empty. No sections (not possible in Microsoft Word)
doc.removeAllChildren();

// Create a new section node
// Note that the section has not yet been added to the document, 
// but we have to specify the parent document
Section section = new Section(doc);

// Append the section to the document
doc.appendChild(section);

// Lets set some properties for the section
section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
section.getPageSetup().setPaperSize(PaperSize.LETTER);

// The section that we created is empty, lets populate it. The section needs at least the Body node
Body body = new Body(doc);
section.appendChild(body);

// The body needs to have at least one paragraph
// Note that the paragraph has not yet been added to the document, 
// but we have to specify the parent document
// The parent document is needed so the paragraph can correctly work
// with styles and other document-wide information
Paragraph para = new Paragraph(doc);
body.appendChild(para);

// We can set some formatting for the paragraph
para.getParagraphFormat().setStyleName("Heading 1");
para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);

// So far we have one empty paragraph in the document
// The document is valid and can be saved, but lets add some text before saving
// Create a new run of text and add it to our paragraph
Run run = new Run(doc);
run.setText("Hello World!");
run.getFont().setColor(Color.RED);
para.appendChild(run);

// As a matter of interest, you can retrieve text of the whole document and
// see that \x000c is automatically appended. \x000c is the end of section character
System.out.println(doc.getText());

// Save the document
doc.save(getArtifactsDir() + "Section.CreateFromScratch.doc");

Property Getters/Setters Detail

getBreakIsStyleSeparator

public boolean getBreakIsStyleSeparator()
True if this paragraph break is a Style Separator. A style separator allows one paragraph to consist of parts that have different paragraph styles.

Example:

Shows how to write text to the same line as a TOC heading and have it not show up in the TOC.
// Create a blank document and insert a table of contents field
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.insertTableOfContents("\\o \\h \\z \\u");
builder.insertBreak(BreakType.PAGE_BREAK);

// Insert a paragraph with a style that will be picked up as an entry in the TOC
builder.getParagraphFormat().setStyleIdentifier(StyleIdentifier.HEADING_1);

// Both these strings are on the same line and same paragraph and will therefore show up on the same TOC entry
builder.write("Heading 1. ");
builder.write("Will appear in the TOC. ");

// Any text on a new line that does not have a heading style will not register as a TOC entry
// If we insert a style separator, we can write more text on the same line
// and use a different style without it showing up in the TOC
// If we use a heading type style afterwards, we can draw two TOC entries from one line of document text
builder.insertStyleSeparator();
builder.getParagraphFormat().setStyleIdentifier(StyleIdentifier.QUOTE);
builder.write("Won't appear in the TOC. ");

// This flag is set to true for such paragraphs
Assert.assertTrue(doc.getFirstSection().getBody().getParagraphs().get(0).getBreakIsStyleSeparator());

// Update the TOC and save the document
doc.updateFields();
doc.save(getArtifactsDir() + "Paragraph.BreakIsStyleSeparator.docx");

getChildNodes

→ inherited from CompositeNode
public NodeCollection getChildNodes()
Gets all immediate child nodes of this node.

Note, ChildNodes is equivalent to calling GetChildNodes(NodeType.Any, false) and creates and returns a new collection every time it is accessed.

If there are no child nodes, this property returns an empty collection.

Example:

Shows how to enumerate immediate children of a CompositeNode using the enumerator provided by the ChildNodes collection.
NodeCollection children = paragraph.getChildNodes();
for (Node child : (Iterable<Node>) children) {
    // Paragraph may contain children of various types such as runs, shapes and so on
    if (child.getNodeType() == NodeType.RUN) {
        // Say we found the node that we want, do something useful
        Run run = (Run) child;
        System.out.println(run.getText());
    }
}

getCount

→ inherited from CompositeNode
public int getCount()
Gets the number of immediate children of this node.

Example:

Shows how to add, update and delete child nodes from within a CompositeNode.
Document doc = new Document();

// An empty document has one paragraph by default
Assert.assertEquals(doc.getFirstSection().getBody().getParagraphs().getCount(), 1);

// A paragraph is a composite node because it can contain runs, which are another type of node
Paragraph paragraph = doc.getFirstSection().getBody().getFirstParagraph();
Run paragraphText = new Run(doc, "Initial text. ");
paragraph.appendChild(paragraphText);

// We will place these 3 children into the main text of our paragraph
Run run1 = new Run(doc, "Run 1. ");
Run run2 = new Run(doc, "Run 2. ");
Run run3 = new Run(doc, "Run 3. ");

// We initialized them but not in our paragraph yet
Assert.assertEquals(paragraph.getText(), "Initial text. " + (char) 12);

// Insert run2 before initial paragraph text. This will be at the start of the paragraph
paragraph.insertBefore(run2, paragraphText);

// Insert run3 after initial paragraph text. This will be at the end of the paragraph
paragraph.insertAfter(run3, paragraphText);

// Insert run1 before every other child node. run2 was the start of the paragraph, now it will be run1
paragraph.prependChild(run1);

Assert.assertEquals(paragraph.getText(), "Run 1. Run 2. Initial text. Run 3. " + (char) 12);
Assert.assertEquals(paragraph.getChildNodes(NodeType.ANY, true).getCount(), 4);

// Access the child node collection and update/delete children
((Run) paragraph.getChildNodes(NodeType.RUN, true).get(1)).setText("Updated run 2. ");
paragraph.getChildNodes(NodeType.RUN, true).remove(paragraphText);

Assert.assertEquals(paragraph.getText(), "Run 1. Updated run 2. Run 3. " + (char) 12);
Assert.assertEquals(paragraph.getChildNodes(NodeType.ANY, true).getCount(), 3);

getDocument

→ inherited from Node
public DocumentBase getDocument()
Gets the document to which this node belongs.

The node always belongs to a document even if it has just been created and not yet added to the tree, or if it has been removed from the tree.

Example:

Shows that when you create any node, it requires a document that will own the node.
// Open a file from disk
Document doc = new Document();

// Creating a new node of any type requires a document passed into the constructor
Paragraph para = new Paragraph(doc);

// The new paragraph node does not yet have a parent
System.out.println("Paragraph has no parent node: " + (para.getParentNode() == null));

// But the paragraph node knows its document
System.out.println("Both nodes' documents are the same: " + (para.getDocument() == doc));

// The fact that a node always belongs to a document allows us to access and modify 
// properties that reference the document-wide data such as styles or lists
para.getParagraphFormat().setStyleName("Heading 1");

// Now add the paragraph to the main text of the first section
doc.getFirstSection().getBody().appendChild(para);

// The paragraph node is now a child of the Body node
System.out.println("Paragraph has a parent node: " + (para.getParentNode() != null));

getFirstChild

→ inherited from CompositeNode
public Node getFirstChild()
Gets the first child of the node. If there is no first child node, a null is returned.

Example:

Shows how to enumerate immediate child nodes of a composite node using NextSibling.
// In this example we enumerate all paragraphs of a section body
// Get the section that we want to work on
Section section = doc.getSections().get(0);
Body body = section.getBody();

// Loop starting from the first child until we reach null
for (Node node = body.getFirstChild(); node != null; node = node.getNextSibling()) {
    // Output the types of the nodes that we come across
    System.out.println(Node.nodeTypeToString(node.getNodeType()));
}

Example:

Shows how to efficiently visit all direct and indirect children of a composite node.
public void recurseAllNodes() throws Exception {
    // Open a document
    Document doc = new Document(getMyDir() + "Document.docx");

    // Invoke the recursive function that will walk the tree
    traverseAllNodes(doc);
}

/**
 * A simple function that will walk through all children of a specified node recursively
 * and print the type of each node to the screen.
 */
@Test(enabled = false)
public void traverseAllNodes(final CompositeNode parentNode) {
    // This is the most efficient way to loop through immediate children of a node
    for (Node childNode = parentNode.getFirstChild(); childNode != null; childNode = childNode.getNextSibling()) {
        // Do some useful work
        System.out.println(Node.nodeTypeToString(childNode.getNodeType()));

        // Recurse into the node if it is a composite node
        if (childNode.isComposite()) {
            traverseAllNodes((CompositeNode) childNode);
        }
    }
}

getFrameFormat

public FrameFormat getFrameFormat()
Provides access to the paragraph formatting properties.

Example:

Shows how to get information about formatting properties of paragraph as frame.
Document doc = new Document(getMyDir() + "Paragraph frame.docx");

ParagraphCollection paragraphs = doc.getFirstSection().getBody().getParagraphs();

for (Paragraph paragraph : (Iterable<Paragraph>) paragraphs) {
    if (paragraph.getFrameFormat().isFrame()) {
        System.out.println("Width: " + paragraph.getFrameFormat().getWidth());
        System.out.println("Height: " + paragraph.getFrameFormat().getHeight());
        System.out.println("HeightRule: " + paragraph.getFrameFormat().getHeightRule());
        System.out.println("HorizontalAlignment: " + paragraph.getFrameFormat().getHorizontalAlignment());
        System.out.println("VerticalAlignment: " + paragraph.getFrameFormat().getVerticalAlignment());
        System.out.println("HorizontalPosition: " + paragraph.getFrameFormat().getHorizontalPosition());
        System.out.println("RelativeHorizontalPosition: " + paragraph.getFrameFormat().getRelativeHorizontalPosition());
        System.out.println("HorizontalDistanceFromText: " + paragraph.getFrameFormat().getHorizontalDistanceFromText());
        System.out.println("VerticalPosition: " + paragraph.getFrameFormat().getVerticalPosition());
        System.out.println("RelativeVerticalPosition: " + paragraph.getFrameFormat().getRelativeVerticalPosition());
        System.out.println("VerticalDistanceFromText: " + paragraph.getFrameFormat().getVerticalDistanceFromText());
    }
}

hasChildNodes

→ inherited from CompositeNode
public boolean hasChildNodes()
Returns true if this node has any child nodes.

isComposite

→ inherited from CompositeNode
public boolean isComposite()
Returns true as this node can have child nodes.

Example:

Shows how to efficiently visit all direct and indirect children of a composite node.
public void recurseAllNodes() throws Exception {
    // Open a document
    Document doc = new Document(getMyDir() + "Document.docx");

    // Invoke the recursive function that will walk the tree
    traverseAllNodes(doc);
}

/**
 * A simple function that will walk through all children of a specified node recursively
 * and print the type of each node to the screen.
 */
@Test(enabled = false)
public void traverseAllNodes(final CompositeNode parentNode) {
    // This is the most efficient way to loop through immediate children of a node
    for (Node childNode = parentNode.getFirstChild(); childNode != null; childNode = childNode.getNextSibling()) {
        // Do some useful work
        System.out.println(Node.nodeTypeToString(childNode.getNodeType()));

        // Recurse into the node if it is a composite node
        if (childNode.isComposite()) {
            traverseAllNodes((CompositeNode) childNode);
        }
    }
}

isDeleteRevision

public boolean isDeleteRevision()
Returns true if this object was deleted in Microsoft Word while change tracking was enabled.

Example:

Shows how to work with revision paragraphs.
// Create a blank document, populate the first paragraph with text and add two more
Document doc = new Document();
Body body = doc.getFirstSection().getBody();
Paragraph para = body.getFirstParagraph();
para.appendChild(new Run(doc, "Paragraph 1. "));
body.appendParagraph("Paragraph 2. ");
body.appendParagraph("Paragraph 3. ");

// We have three paragraphs, none of which registered as any type of revision
// If we add/remove any content in the document while tracking revisions,
// they will be displayed as such in the document and can be accepted/rejected
doc.startTrackRevisions("John Doe", new Date());

// This paragraph is a revision and will have the according "IsInsertRevision" flag set
para = body.appendParagraph("Paragraph 4. ");
Assert.assertTrue(para.isInsertRevision());

// Get the document's paragraph collection and remove a paragraph
ParagraphCollection paragraphs = body.getParagraphs();
Assert.assertEquals(paragraphs.getCount(), 4);
para = paragraphs.get(2);
para.remove();

// Since we are tracking revisions, the paragraph still exists in the document, will have the "IsDeleteRevision" set
// and will be displayed as a revision in Microsoft Word, until we accept or reject all revisions
Assert.assertEquals(paragraphs.getCount(), 4);
Assert.assertTrue(para.isDeleteRevision());

// The delete revision paragraph is removed once we accept changes
doc.acceptAllRevisions();
Assert.assertEquals(paragraphs.getCount(), 3);
Assert.assertEquals(para.getCount(), 0);

isEndOfCell

public boolean isEndOfCell()
True if this paragraph is the last paragraph in a Cell; false otherwise.

Example:

Shows how to set a table to stay together on the same page.
// To keep a table from breaking across a page we need to enable KeepWithNext
// for every paragraph in the table except for the last paragraphs in the last
// row of the table
for (Cell cell : (Iterable<Cell>) table.getChildNodes(NodeType.CELL, true)) {
    for (Paragraph para : cell.getParagraphs()) {
        // Every paragraph that's inside a cell will have this flag set
        Assert.assertTrue(para.isInCell());

        if (!(cell.getParentRow().isLastRow() && para.isEndOfCell())) {

Example:

Shows how to use of methods of Node and CompositeNode to remove a section before the last section in the document.
// Document is a CompositeNode and LastChild returns the last child node in the Document node
// Since the Document can contain only Section nodes, the last child is the last section
Node lastSection = doc.getLastChild();

// Each node knows its next and previous sibling nodes
// Previous sibling of a section is a section before the specified section
// If the node is the first child, PreviousSibling will return null
Node sectionBeforeLast = lastSection.getPreviousSibling();

if (sectionBeforeLast != null) {
    doc.removeChild(sectionBeforeLast);
}

getListFormat

public ListFormat getListFormat()

doc.updateListLabels();
int listParaCount = 1;

for (Paragraph paragraph : (Iterable<Paragraph>) doc.getChildNodes(NodeType.PARAGRAPH, true)) {
    // Find if we have the paragraph list. In our document our list uses plain arabic numbers,
    // which start at three and ends at six
    if (paragraph.getListFormat().isListItem()) {
        System.out.println(MessageFormat.format("Paragraph #{0}", listParaCount));

        // This is the text we get when actually getting when we output this node to text format
        // The list labels are not included in this text output. Trim any paragraph formatting characters
        String paragraphText = paragraph.toString(SaveFormat.TEXT).trim();
        System.out.println("Exported Text: " + paragraphText);

        ListLabel label = paragraph.getListLabel();
        // This gets the position of the paragraph in current level of the list. If we have a list with multiple level then this
        // will tell us what position it is on that particular level
        System.out.println("Numerical Id: " + label.getLabelValue());

        // Combine them together to include the list label with the text in the output
        System.out.println("List label combined with text: " + label.getLabelString() + " " + paragraphText);

        listParaCount++;
    }
}

getNextSibling

→ inherited from Node
public Node getNextSibling()
Gets the node immediately following this node. If there is no next node, a null is returned.

Example:

Shows how to enumerate immediate child nodes of a composite node using NextSibling.
// In this example we enumerate all paragraphs of a section body
// Get the section that we want to work on
Section section = doc.getSections().get(0);
Body body = section.getBody();

// Loop starting from the first child until we reach null
for (Node node = body.getFirstChild(); node != null; node = node.getNextSibling()) {
    // Output the types of the nodes that we come across
    System.out.println(Node.nodeTypeToString(node.getNodeType()));
}

Example:

Shows how to efficiently visit all direct and indirect children of a composite node.
public void recurseAllNodes() throws Exception {
    // Open a document
    Document doc = new Document(getMyDir() + "Document.docx");

    // Invoke the recursive function that will walk the tree
    traverseAllNodes(doc);
}

/**
 * A simple function that will walk through all children of a specified node recursively
 * and print the type of each node to the screen.
 */
@Test(enabled = false)
public void traverseAllNodes(final CompositeNode parentNode) {
    // This is the most efficient way to loop through immediate children of a node
    for (Node childNode = parentNode.getFirstChild(); childNode != null; childNode = childNode.getNextSibling()) {
        // Do some useful work
        System.out.println(Node.nodeTypeToString(childNode.getNodeType()));

        // Recurse into the node if it is a composite node
        if (childNode.isComposite()) {
            traverseAllNodes((CompositeNode) childNode);
        }
    }
}

public int getNodeType()
Returns NodeType.Paragraph. The value of the property is NodeType integer constant.

Example:

Shows how to retrieve the NodeType enumeration of nodes.
Document doc = new Document(getMyDir() + "Document.docx");

// Let's pick a node that we can't be quite sure of what type it is
// In this case lets pick the first node of the first paragraph in the body of the document
Node node = doc.getFirstSection().getBody().getFirstParagraph().getFirstChild();
System.out.println("NodeType of first child: " + Node.nodeTypeToString(node.getNodeType()));

// This time let's pick a node that we know the type of
// Create a new paragraph and a table node
Paragraph para = new Paragraph(doc);
Table table = new Table(doc);

// Access to NodeType for typed nodes will always return their specific NodeType
// i.e A paragraph node will always return NodeType.Paragraph, a table node will always return NodeType.Table
System.out.println("NodeType of Paragraph: " + Node.nodeTypeToString(para.getNodeType()));
System.out.println("NodeType of Table: " + Node.nodeTypeToString(table.getNodeType()));

    RemoveHiddenContentVisitor hiddenContentRemover = new RemoveHiddenContentVisitor();

    // This is the well known Visitor pattern. Get the model to accept a visitor
    // The model will iterate through itself by calling the corresponding methods
    // on the visitor object (this is called visiting)

    // We can run it over the entire the document like so
    doc.accept(hiddenContentRemover);

    // Or we can run it on only a specific node
    Paragraph para = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 4, true);
    para.accept(hiddenContentRemover);

getParagraphFormat

public ParagraphFormat getParagraphFormat()
Provides access to the paragraph formatting properties.

Example:

Creates a simple document from scratch using the Aspose.Words object model.
// Create an "empty" document. Note that like in Microsoft Word, 
// the empty document has one section, body and one paragraph in it
Document doc = new Document();

// This truly makes the document empty. No sections (not possible in Microsoft Word)
doc.removeAllChildren();

// Create a new section node
// Note that the section has not yet been added to the document, 
// but we have to specify the parent document
Section section = new Section(doc);

// Append the section to the document
doc.appendChild(section);

// Lets set some properties for the section
section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
section.getPageSetup().setPaperSize(PaperSize.LETTER);

// The section that we created is empty, lets populate it. The section needs at least the Body node
Body body = new Body(doc);
section.appendChild(body);

// The body needs to have at least one paragraph
// Note that the paragraph has not yet been added to the document, 
// but we have to specify the parent document
// The parent document is needed so the paragraph can correctly work
// with styles and other document-wide information
Paragraph para = new Paragraph(doc);
body.appendChild(para);

// We can set some formatting for the paragraph
para.getParagraphFormat().setStyleName("Heading 1");
para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);

// So far we have one empty paragraph in the document
// The document is valid and can be saved, but lets add some text before saving
// Create a new run of text and add it to our paragraph
Run run = new Run(doc);
run.setText("Hello World!");
run.getFont().setColor(Color.RED);
para.appendChild(run);

// As a matter of interest, you can retrieve text of the whole document and
// see that \x000c is automatically appended. \x000c is the end of section character
System.out.println(doc.getText());

// Save the document
doc.save(getArtifactsDir() + "Section.CreateFromScratch.doc");

getParentNode

→ inherited from Node
public CompositeNode getParentNode()
Gets the immediate parent of this node.

If a node has just been created and not yet added to the tree, or if it has been removed from the tree, the parent is null.

Example:

Shows how to access the parent node.
// Create a new empty document. It has one section
Document doc = new Document();

// The section is the first child node of the document
Node section = doc.getFirstChild();

// The section's parent node is the document
System.out.println("Section parent is the document: " + (doc == section.getParentNode()));

Example:

Shows that when you create any node, it requires a document that will own the node.
// Open a file from disk
Document doc = new Document();

// Creating a new node of any type requires a document passed into the constructor
Paragraph para = new Paragraph(doc);

// The new paragraph node does not yet have a parent
System.out.println("Paragraph has no parent node: " + (para.getParentNode() == null));

// But the paragraph node knows its document
System.out.println("Both nodes' documents are the same: " + (para.getDocument() == doc));

// The fact that a node always belongs to a document allows us to access and modify 
// properties that reference the document-wide data such as styles or lists
para.getParagraphFormat().setStyleName("Heading 1");

// Now add the paragraph to the main text of the first section
doc.getFirstSection().getBody().appendChild(para);

// The paragraph node is now a child of the Body node
System.out.println("Paragraph has a parent node: " + (para.getParentNode() != null));

getParentSection

public Section getParentSection()
Retrieves the parent Section of the paragraph.

Example:

Creates a header and footer using the document object model and insert them into a section.
Document doc = new Document();

HeaderFooter header = new HeaderFooter(doc, HeaderFooterType.HEADER_PRIMARY);
doc.getFirstSection().getHeadersFooters().add(header);

// Add a paragraph with text to the footer
Paragraph para = header.appendParagraph("My header");

Assert.assertTrue(header.isHeader());
Assert.assertTrue(para.isEndOfHeaderFooter());

HeaderFooter footer = new HeaderFooter(doc, HeaderFooterType.FOOTER_PRIMARY);
doc.getFirstSection().getHeadersFooters().add(footer);

// Add a paragraph with text to the footer
para = footer.appendParagraph("My footer");

Assert.assertFalse(footer.isHeader());
Assert.assertTrue(para.isEndOfHeaderFooter());

Assert.assertEquals(para.getParentStory(), footer);
Assert.assertEquals(para.getParentSection(), footer.getParentSection());
Assert.assertEquals(header.getParentSection(), footer.getParentSection());

doc.save(getArtifactsDir() + "HeaderFooter.HeaderFooterCreate.docx");

getParentStory

public Story getParentStory()
Retrieves the parent section-level story that can be Body or HeaderFooter.

Example:

Creates a header and footer using the document object model and insert them into a section.
Document doc = new Document();

HeaderFooter header = new HeaderFooter(doc, HeaderFooterType.HEADER_PRIMARY);
doc.getFirstSection().getHeadersFooters().add(header);

// Add a paragraph with text to the footer
Paragraph para = header.appendParagraph("My header");

Assert.assertTrue(header.isHeader());
Assert.assertTrue(para.isEndOfHeaderFooter());

HeaderFooter footer = new HeaderFooter(doc, HeaderFooterType.FOOTER_PRIMARY);
doc.getFirstSection().getHeadersFooters().add(footer);

// Add a paragraph with text to the footer
para = footer.appendParagraph("My footer");

Assert.assertFalse(footer.isHeader());
Assert.assertTrue(para.isEndOfHeaderFooter());

Assert.assertEquals(para.getParentStory(), footer);

getPreviousSibling

→ inherited from Node
public Node getPreviousSibling()
Gets the node immediately preceding this node. If there is no preceding node, a null is returned.

Example:

Shows how to use of methods of Node and CompositeNode to remove a section before the last section in the document.
// Document is a CompositeNode and LastChild returns the last child node in the Document node
// Since the Document can contain only Section nodes, the last child is the last section
Node lastSection = doc.getLastChild();

// Each node knows its next and previous sibling nodes
// Previous sibling of a section is a section before the specified section
// If the node is the first child, PreviousSibling will return null
Node sectionBeforeLast = lastSection.getPreviousSibling();

if (sectionBeforeLast != null) {
    doc.removeChild(sectionBeforeLast);
}

getRange

→ inherited from Node
public Range getRange()
Returns a Range object that represents the portion of a document that is contained in this node.

Example:

Shows how to delete all characters of a range.
// Insert two sections into a blank document
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.write("Section 1. ");
builder.insertBreak(BreakType.SECTION_BREAK_CONTINUOUS);
builder.write("Section 2.");

// Verify the whole text of the document
Assert.assertEquals("Section 1. \fSection 2.", doc.getText().trim());

// Delete the first section from the document
doc.getSections().get(0).getRange().delete();

// Check the first section was deleted by looking at the text of the whole document again
Assert.assertEquals("Section 2.", doc.getText().trim());

getRuns

public RunCollection getRuns()
Provides access to the typed collection of pieces of text inside the paragraph.

Example:

Shows how to process revision-related properties of Inline nodes.
Document doc = new Document(getMyDir() + "Revision runs.docx");

// This document has 6 revisions
Assert.assertEquals(doc.getRevisions().getCount(), 6);

// The parent node of a revision is the run that the revision concerns, which is an Inline node
Run run = (Run) doc.getRevisions().get(0).getParentNode();

// Get the parent paragraph
Paragraph firstParagraph = run.getParentParagraph();
RunCollection runs = firstParagraph.getRuns();

Assert.assertEquals(runs.getCount(), 6);

// The text in the run at index #2 was typed after revisions were tracked, so it will count as an insert revision
// The font was changed, so it will also be a format revision
Assert.assertTrue(runs.get(2).isInsertRevision());
Assert.assertTrue(runs.get(2).isFormatRevision());

// If one node was moved from one place to another while changes were tracked,
// the node will be placed at the departure location as a "move to revision",
// and a "move from revision" node will be left behind at the origin, in case we want to reject changes
// Highlighting text and dragging it to another place with the mouse and cut-and-pasting (but not copy-pasting) both count as "move revisions"
// The node with the "IsMoveToRevision" flag is the arrival of the move operation, and the node with the "IsMoveFromRevision" flag is the departure point
Assert.assertTrue(runs.get(1).isMoveToRevision());
Assert.assertTrue(runs.get(4).isMoveFromRevision());

// If an Inline node gets deleted while changes are being tracked, it will leave behind a node with the IsDeleteRevision flag set to true until changes are accepted
Assert.assertTrue(runs.get(5).isDeleteRevision());

Method Detail

accept

public boolean accept(DocumentVisitor visitor)
              throws java.lang.Exception
Accepts a visitor.

Enumerates over this node and all of its children. Each node calls a corresponding method on DocumentVisitor.

For more info see the Visitor design pattern.

Calls DocumentVisitor.VisitParagraphStart, then calls Accept for all child nodes of the paragraph and calls DocumentVisitor.VisitParagraphEnd at the end.
Parameters:
visitor - The visitor that will visit the nodes.
Returns:
True if all nodes were visited; false if DocumentVisitor stopped the operation before visiting all nodes.

Example:

Implements the Visitor Pattern to remove all content formatted as hidden from the document.
public void removeHiddenContentFromDocument() throws Exception {
    // Open the document we want to remove hidden content from
    Document doc = new Document(getMyDir() + "Hidden content.docx");

    // Create an object that inherits from the DocumentVisitor class
    RemoveHiddenContentVisitor hiddenContentRemover = new RemoveHiddenContentVisitor();

    // This is the well known Visitor pattern. Get the model to accept a visitor
    // The model will iterate through itself by calling the corresponding methods
    // on the visitor object (this is called visiting)

    // We can run it over the entire the document like so
    doc.accept(hiddenContentRemover);

    // Or we can run it on only a specific node
    Paragraph para = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 4, true);
    para.accept(hiddenContentRemover);

    // Or over a different type of node like below
    Table table = (Table) doc.getChild(NodeType.TABLE, 0, true);
    table.accept(hiddenContentRemover);

appendChild

→ inherited from CompositeNode
public Node appendChild(Node newChild)
Adds the specified node to the end of the list of child nodes for this node.

If the newChild is already in the tree, it is first removed.

If the node being inserted was created from another document, you should use DocumentBase.importNode(com.aspose.words.Node,boolean,int) to import the node to the current document. The imported node can then be inserted into the current document.

Parameters:
newChild - The node to add.
Returns:
The node added.

Example:

Creates a simple document from scratch using the Aspose.Words object model.
// Create an "empty" document. Note that like in Microsoft Word, 
// the empty document has one section, body and one paragraph in it
Document doc = new Document();

// This truly makes the document empty. No sections (not possible in Microsoft Word)
doc.removeAllChildren();

// Create a new section node
// Note that the section has not yet been added to the document, 
// but we have to specify the parent document
Section section = new Section(doc);

// Append the section to the document
doc.appendChild(section);

// Lets set some properties for the section
section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
section.getPageSetup().setPaperSize(PaperSize.LETTER);

// The section that we created is empty, lets populate it. The section needs at least the Body node
Body body = new Body(doc);
section.appendChild(body);

// The body needs to have at least one paragraph
// Note that the paragraph has not yet been added to the document, 
// but we have to specify the parent document
// The parent document is needed so the paragraph can correctly work
// with styles and other document-wide information
Paragraph para = new Paragraph(doc);
body.appendChild(para);

// We can set some formatting for the paragraph
para.getParagraphFormat().setStyleName("Heading 1");
para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);

// So far we have one empty paragraph in the document
// The document is valid and can be saved, but lets add some text before saving
// Create a new run of text and add it to our paragraph
Run run = new Run(doc);
run.setText("Hello World!");
run.getFont().setColor(Color.RED);
para.appendChild(run);

// As a matter of interest, you can retrieve text of the whole document and
// see that \x000c is automatically appended. \x000c is the end of section character
System.out.println(doc.getText());

// Save the document
doc.save(getArtifactsDir() + "Section.CreateFromScratch.doc");

getChild

→ inherited from CompositeNode
public Node getChild(int nodeType, int index, boolean isDeep)
Returns an Nth child node that matches the specified type.

If index is out of range, a null is returned.

Note that markup nodes (NodeType.STRUCTURED_DOCUMENT_TAG and NodeType.SMART_TAG) are traversed even when isDeep = false and GetChild is invoked for non-markup node type. For example if the first run in a para is wrapped in a StructuredDocumentTag, it will still be returned by GetChild(NodeType.Run, 0, false).
Parameters:
nodeType - A NodeType value. Specifies the type of the child node.
index - Zero based index of the child node to select. Negative indexes are also allowed and indicate access from the end, that is -1 means the last node.
isDeep - True to select from all child nodes recursively. False to select only among immediate children. See remarks for more info.
Returns:
The child node that matches the criteria or null if no matching node is found.

Example:

Shows how to test if a node is inside a field by using an XPath expression.
// Let's pick a document we know has some fields in
Document doc = new Document(getMyDir() + "Mail merge destination - Northwind employees.docx");

// Let's say we want to check if the Run below is inside a field
Run run = (Run) doc.getChild(NodeType.RUN, 5, true);

// Evaluate the XPath expression. The resulting NodeList will contain all nodes found inside a field a field (between FieldStart 
// and FieldEnd exclusive). There can however be FieldStart and FieldEnd nodes in the list if there are nested fields 
// in the path. Currently does not find rare fields in which the FieldCode or FieldResult spans across multiple paragraphs
NodeList resultList =
        doc.selectNodes("//FieldStart/following-sibling::node()[following-sibling::FieldEnd]");

// Check if the specified run is one of the nodes that are inside the field
for (Node node : (Iterable<Node>) resultList) {
    if (node == run) {
        System.out.println("The node is found inside a field");
        break;
    }
}

Example:

Shows how to extract a specific child node from a CompositeNode by using the GetChild method and passing the NodeType and index.
Paragraph paragraph = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 0, true);

getChildNodes

→ inherited from CompositeNode
public NodeCollection getChildNodes(int nodeType, boolean isDeep)
Returns a live collection of child nodes that match the specified type.

The collection of nodes returned by this method is always live.

A live collection is always in sync with the document. For example, if you selected all sections in a document and enumerate through the collection deleting the sections, the section is removed from the collection immediately when it is removed from the document.

Parameters:
nodeType - A NodeType value. Specifies the type of nodes to select.
isDeep - True to select from all child nodes recursively. False to select only among immediate children.
Returns:
A live collection of child nodes of the specified type.

Example:

Shows how to get all comments with all replies.
Document doc = new Document(getMyDir() + "Comments.docx");

// Get all comment from the document
NodeCollection comments = doc.getChildNodes(NodeType.COMMENT, true);

// For all comments and replies we identify comment level and info about it
for (Comment comment : (Iterable<Comment>) comments) {
    if (comment.getAncestor() == null) {
        System.out.println("\nThis is a top-level comment");
        System.out.println("Comment author: " + comment.getAuthor());
        System.out.println("Comment text: " + comment.getText());

        for (Comment commentReply : comment.getReplies())
        {
            System.out.println("\n\tThis is a comment reply");
            System.out.println("\tReply author: " + commentReply.getAuthor());
            System.out.println("\tReply text: " + commentReply.getText());
        }
    }
}

Example:

Shows how to extract images from a document and save them as files.

    NodeCollection shapes = doc.getChildNodes(NodeType.SHAPE, true);
    int imageIndex = 0;
    for (Shape shape : (Iterable<Shape>) shapes) {
        if (shape.hasImage()) {
            String imageFileName = MessageFormat.format("File.ExtractImagesToFiles.{0}{1}", imageIndex,
                    FileFormatUtil.imageTypeToExtension(shape.getImageData().getImageType()));
            shape.getImageData().save(getArtifactsDir() + imageFileName);
            imageIndex++;
        }
    }
}

Example:

Demonstrates how to remove a specified TOC from a document.
// Open a document which contains a TOC
Document doc = new Document(getMyDir() + "Table of contents.docx");

// Remove the first TOC from the document

Document doc = new Document();
Paragraph para = doc.getFirstSection().getBody().getFirstParagraph();

// If there are no tab stops in this collection, while we are in this paragraph
// the cursor will jump 36 points each time we press the Tab key in Microsoft Word
Assert.assertEquals(para.getEffectiveTabStops().length, 0);

// We can add custom tab stops in Microsoft Word if we enable the ruler via the view tab
// Each unit on that ruler is two default tab stops, which is 72 points
// Those tab stops can be programmatically added to the paragraph like this
para.getParagraphFormat().getTabStops().add(72.0, TabAlignment.LEFT, TabLeader.DOTS);
para.getParagraphFormat().getTabStops().add(216.0, TabAlignment.CENTER, TabLeader.DASHES);
para.getParagraphFormat().getTabStops().add(360.0, TabAlignment.RIGHT, TabLeader.LINE);

// These tab stops are added to this collection, and can also be seen by enabling the ruler mentioned above
Assert.assertEquals(para.getEffectiveTabStops().length, 3);

// Add a Run with tab characters that will snap the text to our TabStop positions and save the document

remove

→ inherited from Node
public void remove()
Removes itself from the parent.

Example:

Shows how to delete all images from a document.
Document doc = new Document(getMyDir() + "Images.docx");
Assert.assertEquals(doc.getChildNodes(NodeType.SHAPE, true).getCount(), 10);

// Here we get all shapes from the document node, but you can do this for any smaller
// node too, for example delete shapes from a single section or a paragraph
NodeCollection shapes = doc.getChildNodes(NodeType.SHAPE, true);

// We cannot delete shape nodes while we enumerate through the collection
// One solution is to add nodes that we want to delete to a temporary array and delete afterwards
ArrayList shapesToDelete = new ArrayList();
for (Shape shape : (Iterable<Shape>) shapes) {
    // Several shape types can have an image including image shapes and OLE objects
    if (shape.hasImage()) {
        shapesToDelete.add(shape);
    }
}

// Now we can delete shapes
for (Shape shape : (Iterable<Shape>) shapesToDelete) {
    shape.remove();
}

Assert.assertEquals(1, doc.getChildNodes(NodeType.SHAPE, true).getCount());
doc.save(getArtifactsDir() + "Image.DeleteAllImages.docx");

Example:

Shows how to remove all nodes of a specific type from a composite node.
// In this example we remove tables from a section body
// Get the section that we want to work on
Section section = doc.getSections().get(0);
Body body = section.getBody();

// Select the first child node in the body
Node curNode = body.getFirstChild();

while (curNode != null) {
    // Save the pointer to the next sibling node because if the current
    // node is removed from the parent in the next step, we will have
    // no way of finding the next node to continue the loop
    Node nextNode = curNode.getNextSibling();

    // A section body can contain Paragraph and Table nodes
    // If the node is a Table, remove it from the parent
    if (curNode.getNodeType() == NodeType.TABLE) {
        curNode.remove();
    }

    // Continue going through child nodes until null (no more siblings) is reached
    curNode = nextNode;
}

removeAllChildren

→ inherited from CompositeNode
public void removeAllChildren()
Removes all the child nodes of the current node.

Example:

Creates a simple document from scratch using the Aspose.Words object model.
// Create an "empty" document. Note that like in Microsoft Word, 
// the empty document has one section, body and one paragraph in it
Document doc = new Document();

// This truly makes the document empty. No sections (not possible in Microsoft Word)
doc.removeAllChildren();

// Create a new section node
// Note that the section has not yet been added to the document, 
// but we have to specify the parent document
Section section = new Section(doc);

// Append the section to the document
doc.appendChild(section);

// Lets set some properties for the section
section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
section.getPageSetup().setPaperSize(PaperSize.LETTER);

// The section that we created is empty, lets populate it. The section needs at least the Body node
Body body = new Body(doc);
section.appendChild(body);

// The body needs to have at least one paragraph
// Note that the paragraph has not yet been added to the document, 
// but we have to specify the parent document
// The parent document is needed so the paragraph can correctly work
// with styles and other document-wide information
Paragraph para = new Paragraph(doc);
body.appendChild(para);

// We can set some formatting for the paragraph
para.getParagraphFormat().setStyleName("Heading 1");
para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);

// So far we have one empty paragraph in the document
// The document is valid and can be saved, but lets add some text before saving
// Create a new run of text and add it to our paragraph
Run run = new Run(doc);
run.setText("Hello World!");
run.getFont().setColor(Color.RED);
para.appendChild(run);

// As a matter of interest, you can retrieve text of the whole document and
// see that \x000c is automatically appended. \x000c is the end of section character
System.out.println(doc.getText());

// Save the document
doc.save(getArtifactsDir() + "Section.CreateFromScratch.doc");

removeChild

→ inherited from CompositeNode
public Node removeChild(Node oldChild)
Removes the specified child node.

The parent of oldChild is set to null after the node is removed.

Parameters:
oldChild - The node to remove.
Returns:
The removed node.

Example:

Shows how to use of methods of Node and CompositeNode to remove a section before the last section in the document.
// Document is a CompositeNode and LastChild returns the last child node in the Document node
// Since the Document can contain only Section nodes, the last child is the last section
Node lastSection = doc.getLastChild();

// Each node knows its next and previous sibling nodes
// Previous sibling of a section is a section before the specified section
// If the node is the first child, PreviousSibling will return null
Node sectionBeforeLast = lastSection.getPreviousSibling();

if (sectionBeforeLast != null) {
    doc.removeChild(sectionBeforeLast);
}

removeSmartTags

→ inherited from CompositeNode
public void removeSmartTags()
Removes all SmartTag descendant nodes of the current node. This method does not remove the content of the smart tags.

Example:

Removes all smart tags from descendant nodes of the composite node.
Document doc = new Document(getMyDir() + "Document.docx");

// Remove smart tags from the first paragraph in the document
doc.getFirstSection().getBody().getFirstParagraph().removeSmartTags();

selectNodes

→ inherited from CompositeNode
public NodeList selectNodes(java.lang.String xpath)
Selects a list of nodes matching the XPath expression.

Only expressions with element names are supported at the moment. Expressions that use attribute names are not supported.

Parameters:
xpath - The XPath expression.
Returns:
A list of nodes matching the XPath query.

Example:

Shows how to select certain nodes by using an XPath expression.
Document doc = new Document(getMyDir() + "Tables.docx");

// This expression will extract all paragraph nodes which are descendants of any table node in the document
// This will return any paragraphs which are in a table
NodeList nodeList = doc.selectNodes("//Table//Paragraph");

// Iterate through the list with an enumerator and print the contents of every paragraph in each cell of the table
int index = 0;
Iterator<Node> e = nodeList.iterator();
while (e.hasNext()) {
    Node currentNode = e.next();
    System.out.println(MessageFormat.format("Table paragraph index {0}, contents: \"{1}\"", index++, currentNode.getText().trim()));
}

// This expression will select any paragraphs that are direct children of any body node in the document
nodeList = doc.selectNodes("//Body/Paragraph");

// We can treat the list as an array too
Assert.assertEquals(nodeList.toArray().length, 4);

// Use SelectSingleNode to select the first result of the same expression as above
Node node = doc.selectSingleNode("//Body/Paragraph");

Example:

Shows how to test if a node is inside a field by using an XPath expression.
// Let's pick a document we know has some fields in
Document doc = new Document(getMyDir() + "Mail merge destination - Northwind employees.docx");

// Let's say we want to check if the Run below is inside a field
Run run = (Run) doc.getChild(NodeType.RUN, 5, true);

// Evaluate the XPath expression. The resulting NodeList will contain all nodes found inside a field a field (between FieldStart 
// and FieldEnd exclusive). There can however be FieldStart and FieldEnd nodes in the list if there are nested fields 
// in the path. Currently does not find rare fields in which the FieldCode or FieldResult spans across multiple paragraphs
NodeList resultList =
        doc.selectNodes("//FieldStart/following-sibling::node()[following-sibling::FieldEnd]");

// Check if the specified run is one of the nodes that are inside the field
for (Node node : (Iterable<Node>) resultList) {
    if (node == run) {
        System.out.println("The node is found inside a field");
        break;
    }
}

selectSingleNode

→ inherited from CompositeNode
public Node selectSingleNode(java.lang.String xpath)
Selects the first Node that matches the XPath expression.

Only expressions with element names are supported at the moment. Expressions that use attribute names are not supported.

Parameters:
xpath - The XPath expression.
Returns:
The first Node that matches the XPath query or null if no matching node is found.

Example:

Shows how to select certain nodes by using an XPath expression.
Document doc = new Document(getMyDir() + "Tables.docx");

// This expression will extract all paragraph nodes which are descendants of any table node in the document
// This will return any paragraphs which are in a table
NodeList nodeList = doc.selectNodes("//Table//Paragraph");

// Iterate through the list with an enumerator and print the contents of every paragraph in each cell of the table
int index = 0;
Iterator<Node> e = nodeList.iterator();
while (e.hasNext()) {
    Node currentNode = e.next();
    System.out.println(MessageFormat.format("Table paragraph index {0}, contents: \"{1}\"", index++, currentNode.getText().trim()));
}

// This expression will select any paragraphs that are direct children of any body node in the document
nodeList = doc.selectNodes("//Body/Paragraph");

// We can treat the list as an array too
Assert.assertEquals(nodeList.toArray().length, 4);

// Use SelectSingleNode to select the first result of the same expression as above
Node node = doc.selectSingleNode("//Body/Paragraph");

toString

→ inherited from Node
public java.lang.String toString(SaveOptions saveOptions)
               throws java.lang.Exception
Exports the content of the node into a string using the specified save options.
Parameters:
saveOptions - Specifies the options that control how the node is saved.
Returns:
The content of the node in the specified format.

Example:

Exports the content of a node to String in HTML format using custom specified options.
Document doc = new Document(getMyDir() + "Document.docx");

// Extract the last paragraph in the document to convert to HTML
Node node = doc.getLastSection().getBody().getLastParagraph();

// Create an instance of HtmlSaveOptions and set a few options
HtmlSaveOptions saveOptions = new HtmlSaveOptions();
saveOptions.setExportHeadersFootersMode(ExportHeadersFootersMode.PER_SECTION);
saveOptions.setExportRelativeFontSize(true);

// Convert the document to HTML and return as a String. Pass the instance of HtmlSaveOptions to
// to use the specified options during the conversion
String nodeAsHtml = node.toString(saveOptions);

toString

→ inherited from Node
public java.lang.String toString(int saveFormat)
               throws java.lang.Exception
Exports the content of the node into a string in the specified format.
Returns:
The content of the node in the specified format.
Parameters:
saveFormat - A SaveFormat value.

Example:

Shows how to extract the label of each paragraph in a list as a value or a String.
Document doc = new Document(getMyDir() + "Rendering.docx");
doc.updateListLabels();
int listParaCount = 1;

for (Paragraph paragraph : (Iterable<Paragraph>) doc.getChildNodes(NodeType.PARAGRAPH, true)) {
    // Find if we have the paragraph list. In our document our list uses plain arabic numbers,
    // which start at three and ends at six
    if (paragraph.getListFormat().isListItem()) {
        System.out.println(MessageFormat.format("Paragraph #{0}", listParaCount));

        // This is the text we get when actually getting when we output this node to text format
        // The list labels are not included in this text output. Trim any paragraph formatting characters
        String paragraphText = paragraph.toString(SaveFormat.TEXT).trim();
        System.out.println("Exported Text: " + paragraphText);

        ListLabel label = paragraph.getListLabel();
        // This gets the position of the paragraph in current level of the list. If we have a list with multiple level then this
        // will tell us what position it is on that particular level
        System.out.println("Numerical Id: " + label.getLabelValue());

        // Combine them together to include the list label with the text in the output
        System.out.println("List label combined with text: " + label.getLabelString() + " " + paragraphText);

        listParaCount++;
    }
}

Example:

Exports the content of a node to String in HTML format using default options.
Document doc = new Document(getMyDir() + "Document.docx");

// Extract the last paragraph in the document to convert to HTML
Node node = doc.getLastSection().getBody().getLastParagraph();

// When ToString is called using the SaveFormat overload then conversion is executed using default save options
// When saving to HTML using default options the following settings are set:
//   ExportImagesAsBase64 = true
//   CssStyleSheetType = CssStyleSheetType.Inline
//   ExportFontResources = false
String nodeAsHtml = node.toString(SaveFormat.HTML);

Example:

Shows the difference between calling the GetText and ToString methods on a node.
Document doc = new Document();

// Enter a field into the document
DocumentBuilder builder = new DocumentBuilder(doc);
builder.insertField("MERGEFIELD Field");

// GetText will retrieve all field codes and special characters
Assert.assertEquals("\u0013MERGEFIELD Field\u0014«Field»\u0015\f", doc.getText());

// ToString will give us the plaintext version of the document in the save format we put into the parameter
Assert.assertEquals("«Field»\r\n", doc.toString(SaveFormat.TEXT));
