<hr><a name="_details"></a><h2>Detailed Description</h2>
Filters are objects that know how to "filter out" nodes.
<p>
If a <code><a class="el" href="classDOMNodeIterator.html" title="DOMNodeIterators are used to step through a set of nodes, e.g.">DOMNodeIterator</a></code> or <code><a class="el" href="classDOMTreeWalker.html" title="DOMTreeWalker objects are used to navigate a document tree or subtree using the view...">DOMTreeWalker</a></code> is given a <code><a class="el" href="classDOMNodeFilter.html" title="Filters are objects that know how to "filter out" nodes.">DOMNodeFilter</a></code>, it applies the filter before it returns the next node. If the filter says to accept the node, the traversal logic returns it; otherwise, traversal looks for the next node and pretends that the node that was rejected was not there. <p>
The DOM does not provide any filters. <code><a class="el" href="classDOMNodeFilter.html" title="Filters are objects that know how to "filter out" nodes.">DOMNodeFilter</a></code> is just an interface that users can implement to provide their own filters. <p>
<code>DOMNodeFilters</code> do not need to know how to traverse from node to node, nor do they need to know anything about the data structure that is being traversed. This makes it very easy to write filters, since the only thing they have to know how to do is evaluate a single node. One filter may be used with a number of different kinds of traversals, encouraging code reuse. <p>

Constants returned by acceptNode.
<p>
<code>FILTER_ACCEPT:</code> Accept the node. Navigation methods defined for <code><a class="el" href="classDOMNodeIterator.html" title="DOMNodeIterators are used to step through a set of nodes, e.g.">DOMNodeIterator</a></code> or <code><a class="el" href="classDOMTreeWalker.html" title="DOMTreeWalker objects are used to navigate a document tree or subtree using the view...">DOMTreeWalker</a></code> will return this node.<p>
<code>FILTER_REJECT:</code> Reject the node. Navigation methods defined for <code><a class="el" href="classDOMNodeIterator.html" title="DOMNodeIterators are used to step through a set of nodes, e.g.">DOMNodeIterator</a></code> or <code><a class="el" href="classDOMTreeWalker.html" title="DOMTreeWalker objects are used to navigate a document tree or subtree using the view...">DOMTreeWalker</a></code> will not return this node. For <code><a class="el" href="classDOMTreeWalker.html" title="DOMTreeWalker objects are used to navigate a document tree or subtree using the view...">DOMTreeWalker</a></code>, the children of this node will also be rejected. <code>DOMNodeIterators</code> treat this as a synonym for <code>FILTER_SKIP.</code><p>
<code>FILTER_SKIP:</code> Skip this single node. Navigation methods defined for <code><a class="el" href="classDOMNodeIterator.html" title="DOMNodeIterators are used to step through a set of nodes, e.g.">DOMNodeIterator</a></code> or <code><a class="el" href="classDOMTreeWalker.html" title="DOMTreeWalker objects are used to navigate a document tree or subtree using the view...">DOMTreeWalker</a></code> will not return this node.

Since notations are not part of the document tree, they do not appear when traversing over the document tree.<p>
