CustomNodeFilter can be used to define your own NodeFilter for use
with NodeIterators and TreeWalkers. You can create a custom filter
by doing the follwing:
</p>
<p> class MyCustomNodeFilter {
.....
virtual short acceptNode (const Node &n);
.....
}
</p>
<p> Then in your program:
</p>
<p> short MyCustomNodeFilter::acceptNode (const Node &n)
{
if (condition)
return NodeFilter::FILTER_ACCEPT;
else
....
}
</p>
<p></p>
<p> MyCustomFilter *filter = new MyCustomFilter();
NodeFilter nf = NodeFilter::createCutsom(filter);
NodeIterator ni = document.createNodeIterator(document,NodeFilter.SHOW_ALL,nf,false);
</p>
<p> The default implementation of acceptNode() returns NodeFilter::FILTER_ACCEPT
for all nodes.
