Subject AW: Problem with ISO9075 encoded name in XPath Query?
Date Mon, 02 Mar 2009 16:25:25 GMT
Hi Sébastien,

Thanks for your answer. After ISO9075 encoding the XPath query string as well, it now works.

I wasn't aware that I always have to encode the query whether it's already encoded or not.
I thought when I initially encode the node names then I would always have valid paths to use
in the queries straight away.

BR,
Leander
