Available on js

A NodeFilter interface represents an object used to filter the nodes in a NodeIterator or TreeWalker. They don't know anything about the DOM or how to traverse nodes; they just know how to evaluate a single node against the provided filter.

Methods

acceptNode(node:Node):Int

Returns an unsigned short that will be used to tell if a given Node must be accepted or not by the NodeIterator or TreeWalker iteration algorithm. This method is expected to be written by the user of a NodeFilter. Possible return values are:

	<tr>
		<td class="header">Constant</td>
		<td class="header">Description</td>
	</tr>
	<tr>
		<td><code>FILTER_ACCEPT</code></td>
		<td>Value returned by the <code>NodeFilter.acceptNode()</code> method when a node should be accepted.</td>
	</tr>
	<tr>
		<td><code>FILTER_REJECT</code></td>
		<td>Value to be returned by the <code>NodeFilter.acceptNode()</code> method when a node should be rejected. For <code>TreeWalker</code>, child nodes are also rejected. For <code>NodeIterator</code>, this flag is synonymous with FILTER_SKIP.</td>
	</tr>
	<tr>
		<td><code>FILTER_SKIP</code></td>
		<td>Value to be returned by <code>NodeFilter.acceptNode()</code> for nodes to be skipped by the <code>NodeIterator</code> or <code>TreeWalker</code> object. The children of skipped nodes are still considered. This is treated as "skip this node but not its children".</td>
	</tr>
