Property Getters/Setters Detail

• getBackgroundShape/setBackgroundShape

  public Shape getBackgroundShape() / public void setBackgroundShape(Shape value)
  

  Gets or sets the background shape of the document. Can be null.

  Microsoft Word allows only a shape that has its ShapeBase.ShapeType property equal to ShapeType.RECTANGLE to be used as a background shape for a document.

  Microsoft Word supports only the fill properties of a background shape. All other properties are ignored.

  Setting this property to a non-null value will also set the ViewOptions.DisplayBackgroundShape to true.

  Example:

  Shows how to set a background shape for every page of a document.

  Document doc = new Document();
  
  Assert.assertNull(doc.getBackgroundShape());
  
  // The only shape type that we can use as a background is a rectangle.
  Shape shapeRectangle = new Shape(doc, ShapeType.RECTANGLE);
  
  // There are two ways of using this shape as a page background.
  // 1 -  A flat color:
  shapeRectangle.setFillColor(Color.BLUE);
  doc.setBackgroundShape(shapeRectangle);
  
  doc.save(getArtifactsDir() + "DocumentBase.BackgroundShape.FlatColor.docx");
  
  // 2 -  An image:
  shapeRectangle = new Shape(doc, ShapeType.RECTANGLE);
  shapeRectangle.getImageData().setImage(getImageDir() + "Transparent background logo.png");
  
  // Adjust the image's appearance to make it more suitable as a watermark.
  shapeRectangle.getImageData().setContrast(0.2);
  shapeRectangle.getImageData().setBrightness(0.7);
  
  doc.setBackgroundShape(shapeRectangle);
  
  Assert.assertTrue(doc.getBackgroundShape().hasImage());
  
  // Microsoft Word does not support shapes with images as backgrounds,
  // but we can still see these backgrounds in other save formats such as .pdf.
  doc.save(getArtifactsDir() + "DocumentBase.BackgroundShape.Image.pdf");

  ViewOptions.DisplayBackgroundShape, PageColor

• getChildNodes

  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

  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

  public DocumentBase getDocument()
  

• getFirstChild

  public Node getFirstChild()

  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:

      // 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();
          }
      }
  }

• getFontInfos

  public FontInfoCollection getFontInfos()
  

  Provides access to properties of fonts used in this document.

  This collection of font definitions is loaded as is from the document. Font definitions might be optional, missing or incomplete in some documents.

  Do not rely on this collection to ascertain that a particular font is used in the document. You should only use this collection to get information about fonts that might be used in the document.

  Example:

  Shows how to save a document with embedded TrueType fonts.

  Document doc = new Document(getMyDir() + "Document.docx");
  
  FontInfoCollection fontInfos = doc.getFontInfos();
  fontInfos.setEmbedTrueTypeFonts(embedAllFonts);

  Document doc = new Document(getMyDir() + "Embedded font.docx");
  
  FontInfoCollection allFonts = doc.getFontInfos();
  
  // Print all the used and unused fonts in the document.
  for (int i = 0; i < allFonts.getCount(); i++)
  {
      System.out.println("Font index #{i}");
      System.out.println("\tName: {allFonts[i].Name}");

• getParentNode

  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);

  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

  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.

• getWarningCallback/setWarningCallback

  public IWarningCallback getWarningCallback() / public void setWarningCallback(IWarningCallback value)
  

  Called during various document processing procedures when an issue is detected that might result in data or formatting fidelity loss.

  Document may generate warnings at any stage of its existence, so it's important to setup warning callback as early as possible to avoid the warnings loss. E.g. such properties as Document.PageCount actually build the document layout which is used later for rendering, and the layout warnings may be lost if warning callback is specified just for the rendering calls later.

Method Detail

• accept

  public abstract 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.

  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.

• appendChild

  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 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);
  
  // A section needs a body, which will contain all other nodes that can be edited
  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);
  
  // Now we can begin adding content to the document
  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

  public Node deepClone(boolean isCloneChildren)

  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 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());

• getAncestor

  public CompositeNode 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:

• getChild

  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 apply attributes of a table's style directly to the table's elements.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  Table table = builder.startTable();
  builder.insertCell();
  builder.write("Hello world!");
  builder.endTable();
  
  TableStyle tableStyle = (TableStyle)doc.getStyles().add(StyleType.TABLE, "MyTableStyle1");
  tableStyle.setRowStripe(3);
  tableStyle.setCellSpacing(5.0);
  tableStyle.getShading().setBackgroundPatternColor(Color.WHITE);
  tableStyle.getBorders().setColor(Color.BLUE);
  tableStyle.getBorders().setLineStyle(LineStyle.DOT_DASH);
  
  table.setStyle(tableStyle);
  
  // This method concerns table style attributes such as the ones we set above.
  doc.expandTableStylesToDirectFormatting();
  
  doc.save(getArtifactsDir() + "Document.TableStyleToDirectFormatting.docx");

  Example:

  Shows how to enumerate immediate children of a CompositeNode using the enumerator provided by the ChildNodes collection.

  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

  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 print all of a document's comments and their replies.

  Document doc = new Document(getMyDir() + "Comments.docx");
  
  NodeCollection comments = doc.getChildNodes(NodeType.COMMENT, true);
  
  // If a comment has no ancestor, it is a "top-level" comment as opposed to a reply-type comment.
  // Print all top-level comments along with their replies, if there are any.
  for (Comment comment : (Iterable<Comment>) comments)
  {
      if (comment.getAncestor() == null) {
          System.out.println("Top-level comment:");
          System.out.println("\t\"{comment.GetText().Trim()}\", by {comment.Author}");
          System.out.println("Has {comment.Replies.Count} replies");
          for (Comment commentReply : (Iterable<Comment>) comment.getReplies()) {
              System.out.println("\t\"{commentReply.GetText().Trim()}\", by {commentReply.Author}");
          }
          System.out.println();
      }
  }

  Example:

  Shows how to extract images from a document, and save them to the local file system as individual files.

  Document doc = new Document(getMyDir() + "Images.docx");
  
  // Get the collection of shapes from the document,
  // and save the image data of every shape with an image as a file to the local file system.
  NodeCollection shapes = doc.getChildNodes(NodeType.SHAPE, true);
  
  int imageIndex = 0;
  for (Shape shape : (Iterable<Shape>) shapes) {
      if (shape.hasImage()) {
          // The image data of shapes may contain images of many possible image formats. 
          // We can determine a file extension for each image automatically, based on its format.
          String imageFileName = MessageFormat.format("File.ExtractImages.{0}{1}", imageIndex, FileFormatUtil.imageTypeToExtension(shape.getImageData().getImageType()));
          shape.getImageData().save(getArtifactsDir() + imageFileName);
          imageIndex++;
      }
  }

• getText

  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();
  
  DocumentBuilder builder = new DocumentBuilder(doc);
  builder.insertField("MERGEFIELD Field");
  
  // GetText will retrieve the visible text as well as field codes and special characters.
  Assert.assertEquals("\u0013MERGEFIELD Field\u0014«Field»\u0015\f", doc.getText());
  
  // ToString will give us the document's appearance if saved to a passed save format.
  Assert.assertEquals("«Field»\r\n", doc.toString(SaveFormat.TEXT));

• importNode

  public Node importNode(Node srcNode, boolean isImportChildren)

  Imports a node from another document to the current document.

  This method uses the ImportFormatMode.USE_DESTINATION_STYLES option to resolve formatting.

  Importing a node creates a copy of the source node belonging to the importing document. The returned node has no parent. The source node is not altered or removed from the original document.

  Before a node from another document can be inserted into this document, it must be imported. During import, document-specific properties such as references to styles and lists are translated from the original to the importing document. After the node was imported, it can be inserted into the appropriate place in the document using insertBefore(com.aspose.words.Node,com.aspose.words.Node) or insertAfter(com.aspose.words.Node,com.aspose.words.Node).

  If the source node already belongs to the destination document, then simply a deep clone of the source node is created.

  Parameters:

  srcNode - The node being imported.

  isImportChildren - True to import all child nodes recursively; otherwise, false.

  Returns:

  The cloned node that belongs to the current document.

  See Also:

  NodeImporter

  Example:

  Shows how to import a node from one document to another.

  Document srcDoc = new Document();
  Document dstDoc = new Document();
  
  srcDoc.getFirstSection().getBody().getFirstParagraph().appendChild(
      new Run(srcDoc, "Source document first paragraph text."));
  dstDoc.getFirstSection().getBody().getFirstParagraph().appendChild(
      new Run(dstDoc, "Destination document first paragraph text."));
  
  // Every node has a parent document, which is the document that contains the node.
  // Inserting a node into a document that the node does not belong to will throw an exception.
  Assert.assertNotEquals(dstDoc, srcDoc.getFirstSection().getDocument());
  Assert.assertThrows(IllegalArgumentException.class, () -> dstDoc.appendChild(srcDoc.getFirstSection()));
  
  // Use the ImportNode method to create a copy of a node, which will have the document
  // that called the ImportNode method set as its new owner document.
  Section importedSection = (Section)dstDoc.importNode(srcDoc.getFirstSection(), true);
  
  Assert.assertEquals(dstDoc, importedSection.getDocument());
  
  // We can now insert the node into the document.
  dstDoc.appendChild(importedSection);
  
  Assert.assertEquals("Destination document first paragraph text.\r\nSource document first paragraph text.\r\n",
      dstDoc.toString(SaveFormat.TEXT));

• importNode

  public Node importNode(Node srcNode, boolean isImportChildren, int importFormatMode)

  Imports a node from another document to the current document with an option to control formatting.

  This overload is useful to control how styles and list formatting are imported.

  Importing a node creates a copy of the source node belonging to the importing document. The returned node has no parent. The source node is not altered or removed from the original document.

  Before a node from another document can be inserted into this document, it must be imported. During import, document-specific properties such as references to styles and lists are translated from the original to the importing document. After the node was imported, it can be inserted into the appropriate place in the document using insertBefore(com.aspose.words.Node,com.aspose.words.Node) or insertAfter(com.aspose.words.Node,com.aspose.words.Node).

  If the source node already belongs to the destination document, then simply a deep clone of the source node is created.

  Parameters:

  srcNode - The node to imported.

  isImportChildren - True to import all child nodes recursively; otherwise, false.

  importFormatMode - A ImportFormatMode value. Specifies how to merge style formatting that clashes.

  Returns:

  The cloned, imported node. The node belongs to the destination document, but has no parent.

  See Also:

  ImportFormatMode, NodeImporter

  Example:

  Shows how to import node from source document to destination document with specific options.

  // Create two documents, and add a character style to each document.
  // Configure the styles to have the same name, but different text formatting.
  Document srcDoc = new Document();
  Style srcStyle = srcDoc.getStyles().add(StyleType.CHARACTER, "My style");
  srcStyle.getFont().setName("Courier New");
  DocumentBuilder srcBuilder = new DocumentBuilder(srcDoc);
  srcBuilder.getFont().setStyle(srcStyle);
  srcBuilder.writeln("Source document text.");
  
  Document dstDoc = new Document();
  Style dstStyle = dstDoc.getStyles().add(StyleType.CHARACTER, "My style");
  dstStyle.getFont().setName("Calibri");
  DocumentBuilder dstBuilder = new DocumentBuilder(dstDoc);
  dstBuilder.getFont().setStyle(dstStyle);
  dstBuilder.writeln("Destination document text.");
  
  // Import the Section from the destination document into the source document, causing a style name collision.
  // If we use destination styles, then the imported source text with the same style name
  // as destination text will adopt the destination style.
  Section importedSection = (Section)dstDoc.importNode(srcDoc.getFirstSection(), true, ImportFormatMode.USE_DESTINATION_STYLES);
  Assert.assertEquals(dstStyle.getFont().getName(), importedSection.getBody().getFirstParagraph().getRuns().get(0).getFont().getName());
  Assert.assertEquals(dstStyle.getName(), importedSection.getBody().getFirstParagraph().getRuns().get(0).getFont().getStyleName());
  
  // If we use ImportFormatMode.KeepDifferentStyles, the source style is preserved,
  // and the naming clash resolves by adding a suffix.
  dstDoc.importNode(srcDoc.getFirstSection(), true, ImportFormatMode.KEEP_DIFFERENT_STYLES);
  Assert.assertEquals(dstStyle.getFont().getName(), dstDoc.getStyles().get("My style").getFont().getName());
  Assert.assertEquals(srcStyle.getFont().getName(), dstDoc.getStyles().get("My style_0").getFont().getName());

• indexOf

  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

  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 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:

          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());

  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("List item 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("\tNumerical Id: " + label.getLabelValue());
  
          // Combine them together to include the list label with the text in the output
          System.out.println("\tList label combined with text: " + label.getLabelString() + " " + paragraphText);
  
          listParaCount++;
      }
  }

  Example:

  Exports the content of a node to String in HTML format.

  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 html SaveFormat overload then the node is converted directly to html
  Assert.assertEquals("<p style=\"margin-top:0pt; margin-bottom:8pt; line-height:108%; font-size:12pt\">" +
          "<span style=\"font-family:'Times New Roman'\">Hello World!</span>" +
          "</p>", node.toString(SaveFormat.HTML));
  
  // We can also modify the result of this conversion using a SaveOptions object
  HtmlSaveOptions saveOptions = new HtmlSaveOptions();
  saveOptions.setExportRelativeFontSize(true);
  
  Assert.assertEquals("<p style=\"margin-top:0pt; margin-bottom:8pt; line-height:108%\">" +
          "<span style=\"font-family:'Times New Roman'\">Hello World!</span>" +
          "</p>", node.toString(saveOptions));

  Example:

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

  Document doc = new Document();
  
  DocumentBuilder builder = new DocumentBuilder(doc);
  builder.insertField("MERGEFIELD Field");
  
  // GetText will retrieve the visible text as well as field codes and special characters.
  Assert.assertEquals("\u0013MERGEFIELD Field\u0014«Field»\u0015\f", doc.getText());
  
  // ToString will give us the document's appearance if saved to a passed save format.
  Assert.assertEquals("«Field»\r\n", doc.toString(SaveFormat.TEXT));
