Hi Sean, I've been writing batch files to try to do xpath viewing (which I really need to help analyse large large and rapidly changing XML dump I'm formatting) but getting stymied by XSLT's refusal to permit paramterisation of select attributes - I even tried external entities! So if you need a user I'd be interested - I have some java experience but haven't yet tried XSLT from inside java - I've been doing pure XSLT in batch.
