SAX Pull processing?

Hi All,

I was curious if there are any implementations that enable pull sax
parsing? Basically, I want to be able to implement a sax parser where
I can specify it should halt processing if it reaches a certain point,
then pick back up on demand.

Currentlyu I've been playing with the XMLEventReader with stax, but
it'd be nice to find something simpler to use. ;)

Thanks,
James
