Hi,
 
I am facing issue with modifying the xdm document in kamailio 4.0,2 by using xpath(Getting 500 from server). can anyboady suggest me, what is the wrong I am doing based on following example.
 
 
Here is the example for the same.
 
PUT /xcap-root/pidf-manipulation/users/sip:test@kamailio.com/perm-presence/~~/presence/pdm:person?xmlns(pdm=urn:ietf:params:xml:ns:pidf:data-model) HTTP/1.1
Host: kamailio.com
Keep-Alive: 115
Connection: TE, Keep-Alive
TE: trailers
Content-Length: 117
Content-Type: application/xcap-el+xml
 
<pdm:person id = "aa"><op:overriding-willingness><op:basic>closed</op:basic></op:overriding-willingness></pdm:person>
 
HTTP/1.1 500 Server error
Via: SIP/2.0/TCP 192.168.41.60:59958
Server: kamailio (4.0.2 (i386/linux))
Content-Length: 0
 
 
 
And following is the original document which exists in server.
 
GET /xcap-root/pidf-manipulation/users/sip:test@kamailio.com/perm-presence HTTP/1.1
Host: kamailio.com
Keep-Alive: 115
Connection: keep-alive
TE: trailers
 
HTTP/1.1 200 OK
Via: SIP/2.0/TCP 192.168.41.60:59956
ETag: "sr-1377875323-9520-1"
Content-Type: application/pidf+xml
Server: kamailio (4.0.2 (i386/linux))
Content-Length: 683
 
<?xml version = "1.0" encoding = "UTF-8"?><presence xmlns="urn:ietf:params:xml:ns:pidf" xmlns:pdm="urn:ietf:params:xml:ns:pidf:data-model" xmlns:rpid="urn:ietf:params:xml:ns:pidf:rpid" xmlns:op="urn:oma:xml:prs:pidf:oma-pres" xmlns:opd="urn:oma:xml:pde:pidf:ext" xmlns:opd11="urn:oma:xml:pde:pidf:ext:1.1" xmlns:gp="urn:ietf:params:xml:ns:pidf:geopriv10" xmlns:cl="urn:ietf:params:xml:ns:pidf:geopriv10:civicAddr" xmlns:caps="urn:ietf:params:xml:ns:pidf:caps" xmlns:gml="http://www.opengis.net/gml" xmlns:gs="http://www.opengis.net/pidflo/1.0" xmlns:lt="urn:ietf:params:xml:ns:location-type" entity = "sip:test@kamailio.com"><pdm:person id = "aa"></pdm:person></presence>
 
 
I also tried by adding the pdm="urn:ietf:params:xml:ns:pidf:data-model"  to xcap server known namspaces, by using modparam. but still I am getting the same error.
 
 
Thanks for the help.
