I followed your ugly piece of advice (removing the xmlns: part from the text) and now
everything works as expected. Thanks!

there was a wrong internal module name, initially I added the xml
manipulation function as part of presence_xml, but then spit them out and made a dedicated
one. But the name was not updated. The patch is now in 3.2 branch:
http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=3259ef7…
If you cannot update right now, try:
modparam("presence_xml", "xml_ns",
"ri=urn:ietf:params:xml:ns:reginfo")
Not sure if it works if presence_xml is loaded, but if not, it should. 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)
Thanks!
The weird part is that I after adding that modparam get this error message:
loading modules under
/usr/local/lib64/kamailio/modules_k/:/usr/local/lib64/kamailio/modules/
0(65556) ERROR:<core> [modparam.c:162]: set_mod_param_regex: No module

86, column 65: Can't set module parameter
This is on FreeBSD.
If I raise the debug I see the module being loaded and that it registers PVs
0(63596) DEBUG:<core> [mem/q_malloc.c:369]: qm_malloc(0x800c00000, 40) called

Weird stuff.
