Can't wait... Got to have it now. :( I patched xpath.c and created a function which takes a third parameter which are the known namespaces in a space delimited hash list ... I based the patch on some example code from the libxml website which works perfectly from the command line. However, in PostgreSQL, it only works 65% of the time. The other 35% of the time it returns an empty string. I have no idea how to debug that kind of problem.
You make it sound like 8.3 will have full-featured xpath_* frunctions. Will it have full-featured xslt support as well? ----- Original Message ---- From: Nikolay Samokhvalov <[EMAIL PROTECTED]> To: CG <[EMAIL PROTECTED]> Cc: postgresql listserv <pgsql-general@postgresql.org> Sent: Monday, July 9, 2007 4:33:04 PM Subject: Re: [GENERAL] xpath_* namespace bug AFAIK, contrib/xml2 doesn't support namespaces for XPath expressions at all.
