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:

  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");

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

  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()
  

  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

  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 {

          }
      }
  }

• getFrameFormat

  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());

  // 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

• 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());

• 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 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

  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++;
      }
  }

• getEffectiveTabStops

  public TabStop[] getEffectiveTabStops()

  Returns array of all tab stops applied to this paragraph, including applied indirectly by styles or lists.

  Example:

  Shows how to set custom tab stops.

  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
  ParagraphFormat format = doc.getFirstSection().getBody().getFirstParagraph().getParagraphFormat();
  format.getTabStops().add(72.0, TabAlignment.LEFT, TabLeader.DOTS);
  format.getTabStops().add(216.0, TabAlignment.CENTER, TabLeader.DASHES);
  format.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
  para.appendChild(new Run(doc, "\tTab 1\tTab 2\tTab 3"));
  doc.save(getArtifactsDir() + "Paragraph.TabStops.docx");

• getText

  public java.lang.String getText()

  Gets the text of this paragraph including the end of paragraph character.

  The text of all child nodes is concatenated and the end of paragraph character is appended as follows:

  • If the paragraph is the last paragraph of Body, then ControlChar.SECTION_BREAK (\x000c) is appended.
  • If the paragraph is the last paragraph of Cell, then ControlChar.CELL (\x0007) is appended.
  • For all other paragraphs ControlChar.PARAGRAPH_BREAK (\r) is appended.

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

  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);

  Assert.assertEquals(3, paragraph.getChildNodes(NodeType.ANY, true).getCount());

• 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 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.
