TreeWalker.nextNode( ) |
return the next node that is not filtered out |
Availability
DOM Level 2 Traversal
Synopsis
Node nextNode( );
Returns
The node that follows the current node in the document source and is
not filtered out, or null if there is none.
Description
This method sets currentNode to the next node (in
document source order) that is not filtered out and returns that
node. If there is no such node, or if the search for the next node
takes the TreeWalker outside of the root subtree,
currentNode remains unchanged and the method
returns null.
Note that this method "flattens" the document tree
structure and returns nodes in the order in which they appear in the
document source. Calling nextNode( ) may cause the
current node to move down, sideways, or up the document tree. This
type of flattening traversal can also be performed with
NodeIterator.nextNode( ).

This fourth edition of the definitive reference to
JavaScript, a scripting language that can be embedded
directly in web pages, covers the latest version of the
language, JavaScript 1.5, as supported by Netscape 6 and
Internet Explorer 6. The book also provides complete
coverage of the W3C DOM standard (Level 1 and Level 2),
while retaining material on the legacy Level 0 DOM for
backward compatibility.
