   RE: [xml-dev] sax parser and xpath

[ Lists Home | Date Index | Thread Index ]

Yah, if you have room to load the whole doc, then Jaxen can select those
nodes for you with no problem.

Otherwise, I'd use dom4j's ElementHandler, and register to "/x/y/z" and
then maintain your own counter in your handler to do magic upon
every 2nd <z> maybe.

If you are writing SAX code, chances are you're not doing it the easy way.
