public class Cell 
extends CompositeNode

Represents a table cell.

Cell can only be a child of a Row.

Cell can contain block-level nodes Paragraph and Table.

A minimal valid cell needs to have at least one Paragraph.

Example:

Shows how to create a simple table.
Document doc = new Document();

// Tables are placed in the body of a document
Table table = new Table(doc);
doc.getFirstSection().getBody().appendChild(table);

// Tables contain rows, which contain cells,
// which contain contents such as paragraphs, runs and even other tables
// Calling table.EnsureMinimum will also make sure that a table has at least one row, cell and paragraph
Row firstRow = new Row(doc);
table.appendChild(firstRow);

Cell firstCell = new Cell(doc);
firstRow.appendChild(firstCell);

Paragraph paragraph = new Paragraph(doc);
firstCell.appendChild(paragraph);

Run run = new Run(doc, "Hello world!");
paragraph.appendChild(run);

doc.save(getArtifactsDir() + "Table.CreateTable.docx");

Example:

Shows how to iterate through all tables in the document and display the content from each cell.
Document doc = new Document(getMyDir() + "Tables.docx");

// Here we get all tables from the Document node. You can do this for any other composite node
// which can contain block level nodes. For example you can retrieve tables from header or from a cell
// containing another table (nested tables)
TableCollection tables = doc.getFirstSection().getBody().getTables();

// We can make a new array to clone all of the tables in the collection
Assert.assertEquals(tables.toArray().length, 2);

// Iterate through all tables in the document
for (int i = 0; i < tables.getCount(); i++) {
    // Get the index of the table node as contained in the parent node of the table
    System.out.println(MessageFormat.format("Start of Table {0}", i));

    RowCollection rows = tables.get(i).getRows();

    // Iterate through all rows in the table
    for (int j = 0; j < rows.getCount(); j++) {
        System.out.println(MessageFormat.format("\tStart of Row {0}", j));

        CellCollection cells = rows.get(j).getCells();

        // Iterate through all cells in the row
        for (int k = 0; k < cells.getCount(); k++) {
            // Get the plain text content of this cell.
            String cellText = cells.get(k).toString(SaveFormat.TEXT).trim();
            // Print the content of the cell.
            System.out.println(MessageFormat.format("\t\tContents of Cell:{0} = \"{1}\"", k, cellText));
        }

        System.out.println(MessageFormat.format("\tEnd of Row {0}", j));
    }

    System.out.println(MessageFormat.format("End of Table {0}\n", i));
}

Example:

Shows how to build a nested table without using DocumentBuilder.
public void createNestedTable() throws Exception {
    Document doc = new Document();

    // Create the outer table with three rows and four columns
    Table outerTable = createTable(doc, 3, 4, "Outer Table");
    // Add it to the document body
    doc.getFirstSection().getBody().appendChild(outerTable);

    // Create another table with two rows and two columns
    Table innerTable = createTable(doc, 2, 2, "Inner Table");
    // Add this table to the first cell of the outer table
    outerTable.getFirstRow().getFirstCell().appendChild(innerTable);

    doc.save(getArtifactsDir() + "Table.CreateNestedTable.docx");
}

/**
 * Creates a new table in the document with the given dimensions and text in each cell.
 */
private Table createTable(final Document doc, final int rowCount, final int cellCount, final String cellText) throws Exception {
    Table table = new Table(doc);

Constructor Detail

Cell

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

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

To append Cell to the document use InsertAfter or InsertBefore on the row where you want the cell inserted.

Parameters:
doc - The owner document.

Example:

Shows how to build a nested table without using DocumentBuilder.
public void createNestedTable() throws Exception {
    Document doc = new Document();

    // Create the outer table with three rows and four columns
    Table outerTable = createTable(doc, 3, 4, "Outer Table");
    // Add it to the document body
    doc.getFirstSection().getBody().appendChild(outerTable);

    // Create another table with two rows and two columns
    Table innerTable = createTable(doc, 2, 2, "Inner Table");
    // Add this table to the first cell of the outer table
    outerTable.getFirstRow().getFirstCell().appendChild(innerTable);

    doc.save(getArtifactsDir() + "Table.CreateNestedTable.docx");
}

/**

Property Getters/Setters Detail

getCellFormat

public CellFormat getCellFormat()
Provides access to the formatting properties of the cell.

Example:

Shows how to modify formatting of a table cell.
Document doc = new Document(getMyDir() + "Tables.docx");
Table table = (Table) doc.getChild(NodeType.TABLE, 0, true);

// Retrieve the first cell in the table
Cell firstCell = table.getFirstRow().getFirstCell();

// Modify some row level properties
firstCell.getCellFormat().setWidth(30.0); // in points
firstCell.getCellFormat().setOrientation(TextOrientation.DOWNWARD);
firstCell.getCellFormat().getShading().setForegroundPatternColor(Color.GREEN);

doc.save(getArtifactsDir() + "Table.CellFormat.docx");

Example:

Shows how to combine the rows from two tables into one.
// Load the document
Document doc = new Document(getMyDir() + "Tables.docx");

// Get the first and second table in the document
// The rows from the second table will be appended to the end of the first table
Table firstTable = (Table) doc.getChild(NodeType.TABLE, 0, true);
Table secondTable = (Table) doc.getChild(NodeType.TABLE, 1, true);

// Append all rows from the current table to the next
// Due to the design of tables even tables with different cell count and widths can be joined into one table
while (secondTable.hasChildNodes())
    firstTable.getRows().add(secondTable.getFirstRow());

// Remove the empty table container
secondTable.remove();

doc.save(getArtifactsDir() + "Table.CombineTables.docx");

Example:

Shows how to modify the format of rows and cells.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

Table table = builder.startTable();
builder.insertCell();
builder.write("City");
builder.insertCell();
builder.write("Country");
builder.endRow();
builder.insertCell();
builder.write("London");
builder.insertCell();
builder.write("U.K.");
builder.endTable();

// The appearance of rows and individual cells can be edited using the respective formatting objects
RowFormat rowFormat = table.getFirstRow().getRowFormat();
rowFormat.setHeight(25.0);
rowFormat.getBorders().getByBorderType(BorderType.BOTTOM).setColor(Color.RED);

CellFormat cellFormat = table.getLastRow().getFirstCell().getCellFormat();
cellFormat.setWidth(100.0);
cellFormat.getShading().setBackgroundPatternColor(Color.ORANGE);

doc.save(getArtifactsDir() + "Table.RowCellFormat.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.
Document doc = new Document();

Paragraph paragraph = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 0, true);
paragraph.appendChild(new Run(doc, "Hello world!"));
paragraph.appendChild(new Run(doc, " Hello again!"));

NodeCollection children = paragraph.getChildNodes();

// Paragraph may contain children of various types such as runs, shapes and so on
for (Node child : (Iterable<Node>) children)
    if (((child.getNodeType()) == (NodeType.RUN))) {
        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 a CompositeNode's child collection.
Document doc = new Document();

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

// 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("Initial text.", paragraph.getText().trim());

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

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

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 how to create a node and set its owning document.
// 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.
Document doc = new Document(getMyDir() + "Paragraphs.docx");

// Loop starting from the first child until we reach null
for (Node node = doc.getFirstSection().getBody().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 {
    Document doc = new Document(getMyDir() + "Paragraphs.docx");

    // Any node that can contain child nodes, such as the document itself, is composite
    Assert.assertTrue(doc.isComposite());

    // Invoke the recursive function that will go through and print all the child nodes of a composite node
    traverseAllNodes(doc, 0);
}

/// <summary>
/// Recursively traverses a node tree while printing the type of each node with an indent depending on depth as well as the contents of all inline nodes.
/// </summary>
@Test(enabled = false)
public void traverseAllNodes(CompositeNode parentNode, int depth) {
    // Loop through immediate children of a node
    for (Node childNode = parentNode.getFirstChild(); childNode != null; childNode = childNode.getNextSibling()) {
        System.out.println(MessageFormat.format("{0}{1}", String.format("    ", depth), Node.nodeTypeToString(childNode.getNodeType())));

        // Recurse into the node if it is a composite node
        if (childNode.isComposite()) {
            System.out.println();
            traverseAllNodes((CompositeNode) childNode, depth + 1);
        } else if (childNode instanceof Inline) {
            System.out.println(" - \"{childNode.GetText().Trim()}\"");
        } else {
            System.out.println();
        }
    }
}

getFirstParagraph

public Paragraph getFirstParagraph()
Gets the first paragraph among the immediate children.

Example:

Shows how to insert a nested table using DocumentBuilder.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Build the outer table
Cell cell = builder.insertCell();
builder.writeln("Outer Table Cell 1");

builder.insertCell();
builder.writeln("Outer Table Cell 2");

// This call is important in order to create a nested table within the first table
// Without this call the cells inserted below will be appended to the outer table
builder.endTable();

// Move to the first cell of the outer table
builder.moveTo(cell.getFirstParagraph());

// Build the inner table
builder.insertCell();
builder.writeln("Inner Table Cell 1");
builder.insertCell();
builder.writeln("Inner Table Cell 2");

builder.endTable();

doc.save(getArtifactsDir() + "DocumentBuilder.InsertNestedTable.docx");

Example:

Shows how to build a nested table without using DocumentBuilder.
public void createNestedTable() throws Exception {
    Document doc = new Document();

    // Create the outer table with three rows and four columns
    Table outerTable = createTable(doc, 3, 4, "Outer Table");
    // Add it to the document body
    doc.getFirstSection().getBody().appendChild(outerTable);

    // Create another table with two rows and two columns
    Table innerTable = createTable(doc, 2, 2, "Inner Table");
    // Add this table to the first cell of the outer table
    outerTable.getFirstRow().getFirstCell().appendChild(innerTable);

    doc.save(getArtifactsDir() + "Table.CreateNestedTable.docx");

    }

doc.save(getArtifactsDir() + "Table.KeepTableTogether.docx");

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.
Document doc = new Document();

// Get the document's first paragraph and append a child node to it in the form of a run with text
Paragraph para = doc.getFirstSection().getBody().getFirstParagraph();

// When inserting a new node, the document that the node will belong to must be provided as an argument
Run run = new Run(doc, "Hello world!");
para.appendChild(run);

// The node lineage can be traced back to the document itself
Assert.assertEquals(para, run.getParentNode());
Assert.assertEquals(doc.getFirstSection().getBody(), para.getParentNode());
Assert.assertEquals(doc.getFirstSection(), doc.getFirstSection().getBody().getParentNode());
Assert.assertEquals(doc, doc.getFirstSection().getParentNode());

Example:

Shows how to create a node and set its owning document.
// 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));

getParentRow

public Row getParentRow()
Returns the parent row of the cell. Equivalent to (Row)FirstNonMarkupParentNode.

Example:

Shows how to set a table to stay together on the same page.
Document doc = new Document(getMyDir() + "Table spanning two pages.docx");
Table table = (Table) doc.getChild(NodeType.TABLE, 0, true);

// Enabling KeepWithNext for every paragraph in the table except for the last ones in the last row
// will prevent the table from being split across pages 
for (Cell cell : (Iterable<Cell>) table.getChildNodes(NodeType.CELL, true))
    for (Paragraph para : cell.getParagraphs()) {
        Assert.assertTrue(para.isInCell());

        if (!(cell.getParentRow().isLastRow() && para.isEndOfCell()))
            para.getParagraphFormat().setKeepWithNext(true);
    }

doc.save(getArtifactsDir() + "Table.KeepTableTogether.docx");

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 doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Create a second section by inserting a section break and add text to both sections
builder.writeln("Section 1 text.");
builder.insertBreak(BreakType.SECTION_BREAK_CONTINUOUS);
builder.writeln("Section 2 text.");

// Both sections are siblings of each other
Section lastSection = (Section) doc.getLastChild();
Section firstSection = (Section) lastSection.getPreviousSibling();

// Remove a section based on its sibling relationship with another section
if (lastSection.getPreviousSibling() != null)
    doc.removeChild(firstSection);

// The section we removed was the first one, leaving the document with only the second
Assert.assertEquals("Section 2 text.", doc.getText().trim());

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());

getTables

public TableCollection getTables()
Gets a collection of tables that are immediate children of the cell.

Example:

Shows how to find out if a table contains another table or if the table itself is nested inside another table.
public void calculateDepthOfNestedTables() throws Exception {
    Document doc = new Document(getMyDir() + "Nested tables.docx");
    NodeCollection tables = doc.getChildNodes(NodeType.TABLE, true);

    for (int i = 0; i < tables.getCount(); i++) {

        int count = getChildTableCount((Table) tables.get(i));
        System.out.println(MessageFormat.format("Table #{0} has {1} tables directly within its cells", i, count));

        // Now let's try the other way around, lets try find if the table is nested inside another table and at what depth
        int tableDepth = getNestedDepthOfTable((Table) tables.get(i));

        if (tableDepth > 0)

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.VisitCellStart, then calls Accept for all child nodes of the section and calls DocumentVisitor.VisitCellEnd 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:

Traverse a document with a visitor that prints all tables that it encounters.
public void tableToText() throws Exception {
    // Open the document that has tables we want to print the info of
    Document doc = new Document(getMyDir() + "DocumentVisitor-compatible features.docx");

    // Create an object that inherits from the DocumentVisitor class
    TableInfoPrinter visitor = new TableInfoPrinter();

    // Accepting a visitor lets it start traversing the nodes in the document, 
    // starting with the node that accepted it to then recursively visit every child
    doc.accept(visitor);

    // Once the visiting is complete, we can retrieve the result of the operation,
    // that in this example, has accumulated in the visitor
    System.out.println(visitor.getText());

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:

Shows how to construct an Aspose Words document node by node.
Document doc = new Document();

// A newly created blank document still comes one section, one body and one paragraph
// Calling this method will remove all those nodes to completely empty the document
doc.removeAllChildren();

// This document now has no composite nodes that content can be added to
// If we wish to edit it, we will need to repopulate its node collection,
// which we will start to do with by creating a new Section node
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);

Assert.assertEquals("Hello World!" + ControlChar.SECTION_BREAK_CHAR, doc.getText());

doc.save(getArtifactsDir() + "Section.CreateFromScratch.docx");

deepClone

→ inherited from Node
public Node deepClone(boolean isCloneChildren)

Example:

Shows how to clone composite nodes with and without their child nodes.
Document doc = new Document();
Paragraph para = doc.getFirstSection().getBody().getFirstParagraph();
para.appendChild(new Run(doc, "Hello world!"));

// Clone the paragraph and the child nodes
Node cloneWithChildren = para.deepClone(true);

Assert.assertTrue(((CompositeNode) cloneWithChildren).hasChildNodes());
Assert.assertEquals("Hello world!", cloneWithChildren.getText().trim());

// Clone the paragraph without its clild nodes
Node cloneWithoutChildren = para.deepClone(false);

Assert.assertFalse(((CompositeNode) cloneWithoutChildren).hasChildNodes());
Assert.assertEquals("", cloneWithoutChildren.getText().trim());

ensureMinimum

public void ensureMinimum()
If the last child is not a paragraph, creates and appends one empty paragraph.

Example:

Shows how to ensure a cell node is valid.
Document doc = new Document();

// Create a new table and add it to the document
Table table = new Table(doc);
doc.getFirstSection().getBody().appendChild(table);

// Create a new row with a new cell and append it to the table
Row row = new Row(doc);
table.appendChild(row);

Cell cell = new Cell(doc);
row.appendChild(cell);

// Currently, the cell does not contain any cells or nodes that can have content added to them
Assert.assertEquals(0, cell.getChildNodes(NodeType.ANY, true).getCount());

// Ensure the cell has at least one paragraph that we can edit
cell.ensureMinimum();
cell.getFirstParagraph().appendChild(new Run(doc, "Hello world!"));

getAncestor

→ inherited from Node
public CompositeNode getAncestor(int ancestorType)
Gets the first ancestor of the specified NodeType.
Parameters:

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 expand the formatting from styles onto the rows and cells of the table as direct formatting.
Document doc = new Document(getMyDir() + "Tables.docx");
Table table = (Table) doc.getChild(NodeType.TABLE, 0, true);

// First print the color of the cell shading. This should be empty as the current shading
// is stored in the table style
double cellShadingBefore = table.getFirstRow().getRowFormat().getHeight();
System.out.println("Cell shading before style expansion: " + cellShadingBefore);

// Expand table style formatting to direct formatting
doc.expandTableStylesToDirectFormatting();

// Now print the cell shading after expanding table styles. A blue background pattern color
// should have been applied from the table style
double cellShadingAfter = table.getFirstRow().getRowFormat().getHeight();
System.out.println("Cell shading after style expansion: " + cellShadingAfter);

doc.save(getArtifactsDir() + "Document.TableStyleToDirectFormatting.docx");

Example:

Shows how to enumerate immediate children of a CompositeNode using the enumerator provided by the ChildNodes collection.
Document doc = new Document();

Paragraph paragraph = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 0, true);
paragraph.appendChild(new Run(doc, "Hello world!"));
paragraph.appendChild(new Run(doc, " Hello again!"));

NodeCollection children = paragraph.getChildNodes();

// Paragraph may contain children of various types such as runs, shapes and so on
for (Node child : (Iterable<Node>) children)
    if (((child.getNodeType()) == (NodeType.RUN))) {
        Run run = (Run) child;
        System.out.println(run.getText());
    }

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.
Document doc = new Document(getMyDir() + "Images.docx");

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++;
    }
}

Assert.assertEquals(9, imageIndex);

getText

→ inherited from CompositeNode
public java.lang.String getText()
Gets the text of this node and of all its children.

The returned string includes all control and special characters as described in ControlChar.

Example:

Shows how to output all paragraphs in a document that are bulleted or numbered.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.getListFormat().applyNumberDefault();
builder.writeln("Numbered list item 1");
builder.writeln("Numbered list item 2");
builder.writeln("Numbered list item 3");
builder.getListFormat().removeNumbers();

builder.getListFormat().applyBulletDefault();
builder.writeln("Bulleted list item 1");
builder.writeln("Bulleted list item 2");
builder.writeln("Bulleted list item 3");
builder.getListFormat().removeNumbers();

NodeCollection paras = doc.getChildNodes(NodeType.PARAGRAPH, true);
for (Paragraph para : (Iterable<Paragraph>) paras) {
    if (para.getListFormat().isListItem()) {
        System.out.println(java.text.MessageFormat.format("*** A paragraph belongs to list {0}", para.getListFormat().getList().getListId()));
        System.out.println(para.getText());
    }
}

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));

indexOf

→ inherited from CompositeNode
public int indexOf(Node child)
Returns the index of the specified child node in the child node array. Returns -1 if the node is not found in the child nodes.

Example:

Shows how to get the index of a given child node from its parent.
Document doc = new Document(getMyDir() + "Rendering.docx");

// Get the body of the first section in the document
Body body = doc.getFirstSection().getBody();

// Retrieve the index of the last paragraph in the body
Assert.assertEquals(24, body.getChildNodes().indexOf(body.getLastParagraph()));

insertAfter

→ inherited from CompositeNode
public Node insertAfter(Node newChild, Node refChild)
Inserts the specified node immediately after the specified reference node.

If refChild is null, inserts newChild at the beginning of the list of child nodes.

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 insert.
refChild - The Node that is the reference node. The newNode is placed after the refNode.
Returns:
The inserted node.

Example:

Shows how to replace all textboxes with images.
Document doc = new Document(getMyDir() + "Textboxes in drawing canvas.docx");

// This gets a live collection of all shape nodes in the document
NodeCollection shapeCollection = doc.getChildNodes(NodeType.SHAPE, true);

// Since we will be adding/removing nodes, it is better to copy all collection
// into a fixed size array, otherwise iterator will be invalidated
Node[] shapes = shapeCollection.toArray();

for (Node node : shapes) {
    Shape shape = (Shape) node;
    // Filter out all shapes that we don't need
    if (shape.getShapeType() == ShapeType.TEXT_BOX) {
        // Create a new shape that will replace the existing shape
        Shape image = new Shape(doc, ShapeType.IMAGE);

        // Load the image into the new shape
        image.getImageData().setImage(getImageDir() + "Windows MetaFile.wmf");

        // Make new shape's position to match the old shape
        image.setLeft(shape.getLeft());
        image.setTop(shape.getTop());
        image.setWidth(shape.getWidth());
        image.setHeight(shape.getHeight());
        image.setRelativeHorizontalPosition(shape.getRelativeHorizontalPosition());
        image.setRelativeVerticalPosition(shape.getRelativeVerticalPosition());
        image.setHorizontalAlignment(shape.getHorizontalAlignment());
        image.setVerticalAlignment(shape.getVerticalAlignment());
        image.setWrapType(shape.getWrapType());
        image.setWrapSide(shape.getWrapSide());

        // Insert new shape after the old shape and remove the old shape
        shape.getParentNode().insertAfter(image, shape);
        shape.remove();
    }
}

insertBefore

→ inherited from CompositeNode
public Node insertBefore(Node newChild, Node refChild)
Inserts the specified node immediately before the specified reference node.

If refChild is null, inserts newChild at the end of the list of child nodes.

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 insert.
refChild - The Node that is the reference node. The newChild is placed before this node.
Returns:
The inserted node.
