Availability

Synopsis

NodeIterator createNodeIterator(Node root, 
                                unsigned long whatToShow, 
                                NodeFilter filter, 
                                boolean entityReferenceExpansion) 
    throws DOMException;

Arguments

root

The root of the subtree over which the NodeIterator is to iterate.

whatToShow

A bitmask of one or more NodeFilter flags that specify which types of nodes should be returned by this NodeIterator.

filter

An optional node filter function for the NodeIterator, or null for no node filter.

entityReferenceExpansion

true if the NodeIterator should expand entity references in XML documents, or false otherwise.

Returns

A newly created NodeIterator object.

Throws

This method throws a DOMException with a code of NOT_SUPPORTED_ERR if the root argument is null.

Description

This method creates and returns a new NodeIterator object to iterate over 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.
