TreeWalker createTreeWalker(Node root, unsigned long whatToShow, NodeFilter filter, boolean entityReferenceExpansion) throws DOMException;
root
The root of the subtree over which this TreeWalker is to walk.
whatToShow
A bitmask of one or more NodeFilter flags that specify which types of nodes should be returned by this TreeWalker.
filter
An optional node filter function for the TreeWalker, or null for no node filter.
entityReferenceExpansion
true if the TreeWalker should expand entity references in XML documents, or false otherwise.
A newly created TreeWalker object.
This method throws a DOMException with a code of NOT_SUPPORTED_ERR if the root argument is null.
This method creates and returns a new TreeWalker object to traverse the subtree rooted at the root node, using the specified filters.
This method is not actually part of the Document interface but is instead defined by the DocumentTraversal interface. If an implementation supports the Traversal module, the Document object always implements DocumentTraversal and defines this method.
