## Detailed Description

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:

class MyCustomNodeFilter { ..... virtual short acceptNode (const Node &n); ..... }

Then in your program:

short MyCustomNodeFilter::acceptNode (const Node &n) { if (condition) return NodeFilter::FILTER_ACCEPT; else .... }

MyCustomFilter *filter = new MyCustomFilter(); NodeFilter nf = NodeFilter::createCutsom(filter); NodeIterator ni = document.createNodeIterator(document,NodeFilter.SHOW_ALL,nf,false);

The default implementation of acceptNode() returns NodeFilter::FILTER_ACCEPT for all nodes.
