All Implemented Interfaces:

java.lang.Cloneable

public class EditableRangeEnd 
extends 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));

public EditableRangeStart getEditableRangeStart()

Corresponding EditableRangeStart, received by ID.

public int getId() / public void setId(int value)

Specifies the identifier of the editable range.

public boolean isComposite()

Returns true if this node can contain other nodes.

This method returns false as Node cannot 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() + "Node.RecurseAllNodes.doc");

    // 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.
 */
public void traverseAllNodes(CompositeNode parentNode) throws Exception
{
    // 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 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() + "Node.RecurseAllNodes.doc");

    // 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.
 */
public void traverseAllNodes(CompositeNode parentNode) throws Exception
{
    // 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.EDITABLE_RANGE_END. The value of the property is NodeType integer constant.

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));

public Node getPreviousSibling()

Gets the node immediately preceding this node.

If there is no preceding node, a null is returned.

Example:

Demonstrates 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);

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 a section from a Word document.

// Open Word document.
Document doc = new Document(getMyDir() + "Range.DeleteSection.doc");

// The document contains two sections. Each section has a paragraph of text.
System.out.println(doc.getText());

// 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.
System.out.println(doc.getText());

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

Accepts a visitor.

Calls DocumentVisitor.visitEditableRangeEnd(com.aspose.words.EditableRangeEnd).

For more info see the Visitor design pattern.

Parameters:

visitor - The visitor that will visit the node.

Returns:

False if the visitor requested the enumeration to stop.

public Node deepClone(boolean isCloneChildren)
              throws java.lang.Exception

Creates a duplicate of the node.

This method serves as a copy constructor for nodes. The cloned node has no parent, but belongs to the same document as the original node.

This method always performs a deep copy of the node. The isCloneChildren parameter specifies whether to perform copy all child nodes as well.

Parameters:

isCloneChildren - True to recursively clone the subtree under the specified node; false to clone only the node itself.

Returns:

The cloned node.

Example:

Shows how to clone nodes with and without their child nodes.

// Create a new empty document.
Document doc = new Document();

// Add some text to the first paragraph
Paragraph para = doc.getFirstSection().getBody().getFirstParagraph();
para.appendChild(new Run(doc, "Some text"));

// Clone the paragraph and the child nodes.
Node cloneWithChildren = para.deepClone(true);
// Only clone the paragraph and no child nodes.
Node cloneWithoutChildren = para.deepClone(false);

public Node getAncestor(int ancestorType)

Gets the first ancestor of the specified NodeType.

Parameters:

ancestorType - A NodeType value. The node type of the ancestor to retrieve.

Returns:

The ancestor of the specified type or null if no ancestor of this type was found.

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() + "Table.NestedTables.doc");
    int tableIndex = 0;

    for (Table table : (Iterable<Table>) doc.getChildNodes(NodeType.TABLE, true))
    {
        // First lets find if any cells in the table have tables themselves as children.
        int count = getChildTableCount(table);
        System.out.println(MessageFormat.format("Table #{0} has {1} tables directly within its cells", tableIndex, 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);

        if (tableDepth > 0)
            System.out.println(MessageFormat.format("Table #{0} is nested inside another table at depth of {1}", tableIndex, tableDepth));
        else
            System.out.println(MessageFormat.format("Table #{0} is a non nested table (is not a child of another table)", tableIndex));

        tableIndex++;
    }
}

/**

public Node getAncestor(java.lang.Class ancestorType)

Gets the first ancestor of the specified object type.

The ancestor type matches if it is equal to ancestorType or derived from ancestorType.

Parameters:

ancestorType - The object type of the ancestor to retrieve.

Returns:

The ancestor of the specified type or null if no ancestor of this type was found.

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.

See Also:

toTxt()

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(getMyDir() + "Section.CreateFromScratch Out.doc");

public Node nextPreOrder(Node rootNode)

Gets next node according to the pre-order tree traversal algorithm.

Parameters:

rootNode - The top node (limit) of traversal.

Returns:

Next node in pre-order order. Null if reached the rootNode.

Example:

Shows how to delete all images from a document using pre-order tree traversal.

Node curNode = doc;
while (curNode != null)
{
    Node nextNode = curNode.nextPreOrder(doc);

    if (curNode.getNodeType() == NodeType.SHAPE)
    {
        Shape shape = (Shape)curNode;

        // Several shape types can have an image including image shapes and OLE objects.
        if (shape.hasImage())
            shape.remove();
    }

    curNode = nextNode;
}

public Node previousPreOrder(Node rootNode)

Gets the previous node according to the pre-order tree traversal algorithm.

Parameters:

rootNode - The top node (limit) of traversal.

Returns:

Previous node in pre-order order. Null if reached the rootNode.

public void remove()

Removes itself from the parent.

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;
}

Example:

Shows how to delete all images from a document.

// 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();

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.doc");

// 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);

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() + "Lists.PrintOutAllLists.doc");
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:

Shows the difference between calling the GetText and ToString methods on a node.

Document doc = new Document();

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

// GetText will retrieve all field codes and special characters
System.out.println("GetText() Result: " + doc.getText());

// ToString will export the node to the specified format. When converted to text it will not retrieve fields code
// or special characters, but will still contain some natural formatting characters such as paragraph markers etc.
// This is the same as "viewing" the document as if it was opened in a text editor.
System.out.println("ToString() Result: " + doc.toString(SaveFormat.TEXT));

Example:

Exports the content of a node to string in HTML format using default options.

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

// 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);

public java.lang.String toTxt()
            throws java.lang.Exception

Exports the content of the node into a string in plain text format.

This method removes field codes and Microsoft Word control characters, uses CrLf (or any other) combination of characters to mark ends of paragraphs in the resulting string. It produces a different result from getText() which just gets the text from the node without removing field codes or special characters.

Returns:

The content of the node in plain text format.
