Re: [SR-Users] XMLOPS xpath issues

Hello, an xpath invalid expression should be printed when the xpath expression is incorrect -- I cannot say what is wrong, not being an xpath expert by hart. However, there is a mismatching between the xml standards and SIP/SIMPLE specs. In XML, the namespaces are bound to prefixes, while the guys at IETF added by their own so called default namespace, which has no prefix for it. That results in not being able to use directly xpath from libxml2 with SIMPLE bodies. There were some discussions out there (you can google, iirc Inaki was in couple of them), in one side, the devs of libxml2 said they don't want to break XML standards by allowing bogus xpath queries with such namespaces. The workaround is to define xmlns prefix in xmlops module: http://kamailio.org/docs/modules/devel/modules/xmlops.html#xml_ns modparam("xmlops", "xml_ns", "ri=urn:ietf:params:xml:ns:reginfo") and try: $xml(pub=>xpath://ri:reginfo/ri:registration@aor)
