This kind usage of xmlns in an xml doc is a hack done by SIMPLE WG 
breaking XML standard, because any ns has to use a prefix for each 
corresponding name. If you search on google, you will fine some 
discussions on the web (iirc, Inaki was there as well) - libxml2 devs 
said they don't want to break the xml standard to handle this case, 
probably they didn't change the mind meanwhile.

Anyhow, set a prefix for the namespace via xml_ns parameter and then use 
it in xpath

modparam("xmlops", "xml_ns", "di=urn:ietf:params:xml:ns:dialog-info")


Hope i remembered correctly, anyhow it is somewhere in this direction. 
If not, search on mailing list archive, the situation popped up few 
times around.
