Re: Problem to Xquery a document from xindice collection

Hi,

Did you try the same query using the commandline Xindice to see if your
xpath query works? That helps me in firguring out my problems. I am doing
the same type of stuff and compared our code - yours is the same as mine so
it should work.

PS Good luck meeting your deadline!
