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 following:
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::createCustom(filter); NodeIterator ni = document.createNodeIterator(document,NodeFilter.SHOW_ALL,nf,false);
The default implementation of acceptNode() returns NodeFilter::FILTER_ACCEPT for all nodes.
