[xquery-talk] XPath parser in Java

[Kevin Fandre]

There are few xpath javacc/jjtree grammars floating around that you can use
to generate your own parser. I used one a few years back to build an xpath
-> object-relational sql translater. If you dont find one, and your
interested, email mail me and I'll send you a grammar.
