Property Getters/Setters Detail |
---|
isComposite | |
public boolean isComposite() |
hasChildNodes | |
public boolean hasChildNodes() |
getChildNodes | |
public NodeCollection getChildNodes() |
If there are no child nodes, this property returns an empty collection.
ChildNodes is equivalent to calling GetChildNodes(NodeType.Any, false)
.
getFirstChild | |
public Node getFirstChild() |
getLastChild | |
public Node getLastChild() |
getCount | |
public int getCount() |
getNodeType | → inherited from Node |
public abstract 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.
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.
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.
getNextSibling | → inherited from Node |
public Node getNextSibling() |
getRange | → inherited from Node |
public Range getRange() |
Method Detail |
---|
iterator | |
public java.util.Iterator iterator() |
getText | |
public java.lang.String getText() |
The returned string includes all control and special characters as described in
accept | → inherited from Node |
public abstract boolean accept(DocumentVisitor visitor) throws java.lang.Exception |
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.
visitor
- The visitor that will visit the nodes.deepClone | |
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.getChildNodes | |
public NodeCollection getChildNodes(int nodeType, boolean isDeep) |
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.
nodeType
- A isDeep
- True to select from all child nodes recursively.
False to select only among immediate children. getChildNodes | |
public NodeCollection getChildNodes(int nodeType, boolean isDeep, boolean isLive) |
Snapshot collections require less resources than live collections because a snapshot collection of nodes is not updated when the document is changed.
Snapshot collections are useful for tasks, that do not require immediate update of the collection when the document is changed. For example, select all shapes and delete them is more efficient using a snapshot collection.
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.
nodeType
- A isDeep
- True to select from all child nodes recursively.
False to select only among immediate children. isLive
- True to return a live collection; false to return a snapshot collection.getChild | |
public Node getChild(int nodeType, int index, boolean isDeep) |
If index is out of range, a null is returned.
nodeType
- A 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. selectNodes | |
public NodeList selectNodes(java.lang.String xpath) throws org.jaxen.JaxenException |
Only expressions with element names are supported at the moment. Expressions that use attribute names are not supported.
xpath
- The XPath expression.selectSingleNode | |
public Node selectSingleNode(java.lang.String xpath) throws org.jaxen.JaxenException |
Only expressions with element names are supported at the moment. Expressions that use attribute names are not supported.
xpath
- The XPath expression.appendChild | |
public Node appendChild(Node newChild) throws java.lang.Exception |
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
newChild
- The node to add.prependChild | |
public Node prependChild(Node newChild) throws java.lang.Exception |
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
newChild
- The node to add.insertAfter | |
public Node insertAfter(Node newChild, Node refChild) throws java.lang.Exception |
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
newChild
- The Node to insert.refChild
- The Node that is the reference node. The newNode is placed after the refNode. insertBefore | |
public Node insertBefore(Node newChild, Node refChild) throws java.lang.Exception |
If refChild is null, inserts newChild at the end of the list of child nodes.
Note: InsertBefore could be slower than InsertAfter because it needs to iterate over all nodes from the first child to the reference 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
newChild
- The Node to insert.refChild
- The Node that is the reference node. The newChild is placed before this node.removeChild | |
public Node removeChild(Node oldChild) throws java.lang.Exception |
The parent of oldChild is set to null after the node is removed.
oldChild
- The node to remove.removeAllChildren | |
public void removeAllChildren() throws java.lang.Exception |
indexOf | |
public int indexOf(Node child) |
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 type of the ancestor to retrieve.remove | → inherited from Node |
public void remove() throws java.lang.Exception |
nextPreOrder | → inherited from Node |
public Node nextPreOrder(Node rootNode) |
rootNode
- The top node (limit) of traversal.previousPreOrder | → inherited from Node |
public Node previousPreOrder(Node rootNode) |
rootNode
- The top node (limit) of traversal.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 combination
to mark ends of paragraphs in the resulting string. It produces a different result from
