I have to parse big XML and I am using STAX Parser for creating events as its performance is best.

But, I am ending up writing lot of code for setting booleans in order to parse XML. I am now thinking to use XPath to extract XML fragments and submit XML chunk so created to XMLBeans.

Please suggest if this is a good approach of using XPath and STAX together for this and some resources/link on how to do this.
