com.aspose.words.SpecialChar
public class SpecialChar
A Microsoft Word document can include a number of special characters
that represent fields, form fields, shapes, OLE objects, footnotes etc. For the list
of special characters see SpecialChar is an inline-node and can only be a child of Paragraph. SpecialChar char is used as a base class for more specific classes
that represent special characters that Aspose.Words provides programmatic access for.
The SpecialChar class is also used itself to represent special character for which
Aspose.Words does not provide detailed programmatic access.

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 pararagraph 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 \u000c is automatically appended. \u000c is the end of section character. Assert.assertEquals("Hello World!\u000c", doc.getText()); // Save the document. doc.save(getMyDir() + "Section.CreateFromScratch Out.doc");

getDirectRunAttrsCount | → inherited from Inline |
public int getDirectRunAttrsCount() |
getParentNode | → inherited from Node |
public CompositeNode getParentNode() |
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. Assert.assertEquals(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. Assert.assertNull(para.getParentNode()); // But the paragraph node knows its document. Assert.assertEquals(doc, para.getDocument()); // 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 paragaph to the main text of the first section. doc.getFirstSection().getBody().appendChild(para); // The paragraph node is now a child of the Body node. Assert.assertNotNull(para.getParentNode());
getDocument | → inherited from Node |
public Document getDocument() |
The node always belongs to a document even if it has just been created and not yed 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. Assert.assertNull(para.getParentNode()); // But the paragraph node knows its document. Assert.assertEquals(doc, para.getDocument()); // 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 paragaph to the main text of the first section. doc.getFirstSection().getBody().appendChild(para); // The paragraph node is now a child of the Body node. Assert.assertNotNull(para.getParentNode());
getPreviousSibling | → inherited from Node |
public Node getPreviousSibling() |
If there is no preceding node, a null is returned.
Note: Calculating the value of this property iterates from the first child node of ParenNode to this node.
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);
getNextSibling | → inherited from Node |
public Node getNextSibling() |
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.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); } /// <summary> /// A simple function that will walk through all children of a specified node recursively /// and print the type of each node to the screen. /// </summary> private void TraverseAllNodes(CompositeNode parentNode) { // This is the most efficient way to loop through immediate children of a node. for (Node childNode = parentNode.getFirstChild(); childNode != null; childNode = childNode.getNextSibling()) { // Do some useful work. System.out.println(childNode.getNodeType()); // Recurse into the node if it is a composite node. if (childNode.isComposite()) TraverseAllNodes((CompositeNode)childNode); } }
isComposite | → inherited from Node |
public boolean isComposite() |
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); } /// <summary> /// A simple function that will walk through all children of a specified node recursively /// and print the type of each node to the screen. /// </summary> private void TraverseAllNodes(CompositeNode parentNode) { // This is the most efficient way to loop through immediate children of a node. for (Node childNode = parentNode.getFirstChild(); childNode != null; childNode = childNode.getNextSibling()) { // Do some useful work. System.out.println(childNode.getNodeType()); // Recurse into the node if it is a composite node. if (childNode.isComposite()) TraverseAllNodes((CompositeNode)childNode); } }

accept | |
public boolean accept(DocumentVisitor visitor) throws java.lang.Exception |
Calls DocumentVisitor.VisitSpecialChar.
For more info see the Visitor design pattern.
visitor
- The visitor that will visit the node.getText | |
public java.lang.String getText() |
deepClone | → inherited from Inline |
public Node deepClone(boolean isCloneChildren) throws java.lang.Exception |
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.
isCloneChildren
- True to recursively clone the subtree under the specified node;
false to clone only the node itself.getDirectRunAttr | → inherited from Inline |
public java.lang.Object getDirectRunAttr(int fontAttr) |

public Node getAncestor(int ancestorType) |
ancestorType
- A remove | → inherited from Node |
public void remove() throws java.lang.Exception |
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; }
