BookmarkStart
Inheritance: java.lang.Object, com.aspose.words.Node
public class BookmarkStart extends Node
Represents a start of a bookmark in a Word document.
To learn more, visit the Working with Bookmarks documentation article.
Remarks:
A complete bookmark in a Word document consists of a BookmarkStart and a matching BookmarkEnd with the same bookmark name.
BookmarkStart and BookmarkEnd are just markers inside a document that specify where the bookmark starts and ends.
Use the getBookmark() class as a “facade” to work with a bookmark as a single object.
Examples:
Shows how to add bookmarks and update their contents.
public void createUpdateAndPrintBookmarks() throws Exception {
// Create a document with three bookmarks, then use a custom document visitor implementation to print their contents.
Document doc = createDocumentWithBookmarks(3);
BookmarkCollection bookmarks = doc.getRange().getBookmarks();
printAllBookmarkInfo(bookmarks);
// Bookmarks can be accessed in the bookmark collection by index or name, and their names can be updated.
bookmarks.get(0).setName("{bookmarks[0].Name}_NewName");
bookmarks.get("MyBookmark_2").setText("Updated text contents of {bookmarks[1].Name}");
// Print all bookmarks again to see updated values.
printAllBookmarkInfo(bookmarks);

dd()
public void dd()
deepClone(boolean isCloneChildren)
public Node deepClone(boolean isCloneChildren)
Creates a duplicate of the node.
Remarks:
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.
Examples:
Shows how to clone a composite node.
Document doc = new Document();
Paragraph para = doc.getFirstSection().getBody().getFirstParagraph();
para.appendChild(new Run(doc, "Hello world!"));
// Below are two ways of cloning a composite node.
// 1 - Create a clone of a node, and create a clone of each of its child nodes as well.
Node cloneWithChildren = para.deepClone(true);
Assert.assertTrue(((CompositeNode) cloneWithChildren).hasChildNodes());
Assert.assertEquals("Hello world!", cloneWithChildren.getText().trim());
// 2 - Create a clone of a node just by itself without any children.
Node cloneWithoutChildren = para.deepClone(false);
Assert.assertFalse(((CompositeNode) cloneWithoutChildren).hasChildNodes());
Assert.assertEquals("", cloneWithoutChildren.getText().trim());
Parameters:
Parameter | Type | Description |
---|---|---|
isCloneChildren | boolean | True to recursively clone the subtree under the specified node; false to clone only the node itself. |
Returns: Node - The cloned node.
getAncestor(int ancestorType)
public CompositeNode getAncestor(int ancestorType)
Parameters:
Parameter | Type | Description |
---|---|---|
ancestorType | int |
Returns: CompositeNode
getAncestor(Class ancestorType)
public CompositeNode getAncestor(Class ancestorType)
Gets the first ancestor of the specified object type.
Remarks:
The ancestor type matches if it is equal to ancestorType or derived from ancestorType .

int tableDepth = getNestedDepthOfTable(table);
if (tableDepth > 0)

else
System.out.println(MessageFormat.format("Table #{0} is a non nested table (is not a child of another table)", i));
}
}
// 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(final Table table) {
int depth = 0;
Node parent = table.getAncestor(table.getNodeType());
while (parent != null) {
depth++;
parent = parent.getAncestor(Table.class);
}
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 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(final Table table) {
int childTableCount = 0;
for (Row row : table.getRows()) {
for (Cell cell : row.getCells()) {
TableCollection childTables = cell.getTables();
if (childTables.getCount() > 0) childTableCount++;
}
}
return childTableCount;
}
Parameters:
Parameter | Type | Description |

// Note that the 'CustomNodeId' is not saved to an output file and exists only during the node lifetime.
shape.setCustomNodeId(100);
shape.setWrapType(WrapType.INLINE);
paragraph.appendChild(shape);
paragraph.appendChild(new Run(doc, "Hello again!"));
// Iterate through the paragraph's collection of immediate children,
// and print any runs or shapes that we find within.

Shows how to create a node and set its owning document.
Document doc = new Document();
Paragraph para = new Paragraph(doc);
para.appendChild(new Run(doc, "Hello world!"));
// We have not yet appended this paragraph as a child to any composite node.
Assert.assertNull(para.getParentNode());
// If a node is an appropriate child node type of another composite node,
// we can attach it as a child only if both nodes have the same owner document.
// The owner document is the document we passed to the node's constructor.
// We have not attached this paragraph to the document, so the document does not contain its text.

// Note that the 'CustomNodeId' is not saved to an output file and exists only during the node lifetime.
shape.setCustomNodeId(100);
shape.setWrapType(WrapType.INLINE);
paragraph.appendChild(shape);
paragraph.appendChild(new Run(doc, "Hello again!"));
// Iterate through the paragraph's collection of immediate children,
// and print any runs or shapes that we find within.
NodeCollection children = paragraph.getChildNodes(NodeType.ANY, false);
Assert.assertEquals(3, paragraph.getChildNodes(NodeType.ANY, false).getCount());
for (Node child : (Iterable) children)
switch (child.getNodeType()) {
case NodeType.RUN:
System.out.println("Run contents:");
System.out.println(MessageFormat.format("\t\"{0}\"", child.getText().trim()));
