getDocument | → inherited from Node |
public DocumentBase getDocument() |
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));
getEditableRangeStart | |
public EditableRangeStart getEditableRangeStart() |
getId/setId | |
public int getId() / public void setId(int value) |
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); } /** * 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); } }
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.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); } }
getNodeType | |
public int getNodeType() |
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. 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));
getPreviousSibling | → inherited from Node |
public Node getPreviousSibling() |
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);
getRange | → inherited from Node |
public Range getRange() |
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());
Method Detail |

accept | |
public boolean accept(DocumentVisitor visitor) throws java.lang.Exception |
Calls
For more info see the Visitor design pattern.
visitor
- The visitor that will visit the node.deepClone | → inherited from Node |
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.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);
getAncestor | → inherited from Node |
public Node getAncestor(int ancestorType) |
ancestorType
- A 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++; } } /** * Calculates what level a table is nested inside other tables. * * @returns An integer containing the level the table is nested at. * 0 = Table is not nested inside any other table * 1 = Table is nested within one parent table * 2 = Table is nested within two parent tables etc.. */ private static int getNestedDepthOfTable(Table table) throws Exception { int depth = 0; int type = table.getNodeType(); // The parent of the table will be a Cell, instead attempt to find a grandparent that is of type Table Node parent = table.getAncestor(type); while (parent != null) { // Every time we find a table a level up we increase the depth counter and then try to find an // ancestor of type table from the parent. depth++; parent = parent.getAncestor(type); } return depth; } /** * Determines if a table contains any immediate child table within its cells. * Does not recursively traverse through those tables to check for further tables. * @returns Returns true if at least one child cell contains a table. * Returns false if no cells in the table contains a table. */ private static int getChildTableCount(Table table) throws Exception { int tableCount = 0; // Iterate through all child rows in the table for (Row row : table.getRows()) { // Iterate through all child cells in the row for (Cell Cell : row.getCells()) { // Retrieve the collection of child tables of this cell TableCollection childTables = Cell.getTables(); // If this cell has a table as a child then return true if (childTables.getCount() > 0) tableCount++; } } // No cell contains a table return tableCount; }
getAncestor | → inherited from Node |
public Node getAncestor(java.lang.Class ancestorType) |
The ancestor type matches if it is equal to ancestorType or derived from ancestorType.
ancestorType
- The object type of the ancestor to retrieve.getText | → inherited from Node |
public java.lang.String getText() |
The returned string includes all control and special characters as described in
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");
nextPreOrder | → inherited from Node |
public Node nextPreOrder(Node rootNode) |
rootNode
- The top node (limit) of traversal.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; }
previousPreOrder | → inherited from Node |
public Node previousPreOrder(Node rootNode) |
rootNode
- The top node (limit) of traversal.remove | → inherited from Node |
public void remove() |
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();
toString | → inherited from Node |
public java.lang.String toString(SaveOptions saveOptions) throws java.lang.Exception |
saveOptions
- Specifies the options that control how the node is saved.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);
toString | → inherited from Node |
public java.lang.String toString(int saveFormat) throws java.lang.Exception |
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);
toTxt | → inherited from Node |
public java.lang.String toTxt() throws java.lang.Exception |
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
