Hi,<BR>
<BR>
The full log helped me see what is going on. Rather embarassingly it is a Linux command line or curl error. This command:<BR>
<BR>
curl --digest -u 111:111 -T pidf_modify.xml -H "Content-Type: application/xcap-el+xml" -X PUT <A HREF="http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:111@multifon.ru/index~~/presence/tuple%5b@id=">http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:111@multifon.ru/index~~/presence/tuple%5b@id=</A>'x8eg92n'%5d/note<BR>
<BR>
doesn't work, but this command:<BR>
<BR>
curl --digest -u 111:111 -T pidf_modify.xml -H "Content-Type: application/xcap-el+xml" -X PUT <A HREF="http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:111@multifon.ru/index~~/presence/tuple%5b@id=">http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:111@multifon.ru/index~~/presence/tuple%5b@id=</A>\'x8eg92n\'%5d/note<BR>
<BR>
does.<BR>
<BR>
Something was removing the ' characters from the URL.<BR>
<BR>
Thanks,<BR>

Hello,<BR>
<BR>
can you give the full log of such operation with debug=3? It may help seeing the values used internally for matching...<BR>
<BR>
Otherwise, if it is a valid xpath condition and no match, then could be something to libxml2 implementation.<BR>
<BR>
Cheers,<BR>

Hi,<BR>
<BR>
I tried a simplified update URL with curl: curl --digest -u 111:111 -T pidf_modify.xml -H "Content-Type: application/xcap-el+xml" -X PUT <A HREF="http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:111@mydomain/index%7E%7E/presence/tuple/note">http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:111@mydomain/index~~/presence/tuple/note</A><BR>
<BR>
This "correctly" updated the <note/> nodes in both <tuple/> nodes of the document. So, the problem with the XCAP server appears to be over the %<A HREF="mailto:5b@id=">5b@id=</A>'x8eg92n'%5d that is used to identify a specific <tuple/> node. I believe, from searching online, that this is valid XPath syntax, so it does look like there is a bug here.<BR>
<BR>
Any idea?<BR>
<BR>
Thanks,<BR>
<BR>

Hi,<BR>
<BR>
I have been experimenting with uploading, and modifying existing, XCAP documents. I have been trying out the example from RFC 4827 and I can't get it to work with Kamailio.<BR>
<BR>
To upload the document (this works) I use the command: curl --digest -u 111:111 -T pidf.xml -X PUT <A HREF="http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:111@multifon.ru/index">http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:111@mydomain/index</A><BR>
<BR>
To modify the document (this doesn't work) I use the command: curl --digest -u 111:111 -T pidf_modify.xml -H "Content-Type: application/xcap-el+xml" -X PUT <A HREF="http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:111@multifon.ru/index%7E%7E/presence/tuple%5b@id=%27x8eg92n%27%5d/note">http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:111@mydomain/index~~/presence/tuple%5b@id='x8eg92n'%5d/note</A><BR>
<BR>
When I try to modify the document I get the error: "Apr 4 17:12:08 pd-laptop-linux kamailio[16862]: ERROR: xcap_server [xcap_server.c:596]: no new content"<BR>
<BR>
I went through the XCAP server code and added some debug and found that the check on xcap_misc.c:491 is succeeding (which means "no selection for xpath parent expression") and the document is not being changed. Also, from my limited understanding of XPath and libxml2, I would have expected the code path which should have been followed to go through the else clause of the conditional on xcap_misc.c:468 - which means I don't think that the xcaps_xpath_set() function is doing the right thing at all.<BR>
<BR>
Is there anyone here that is more familiar with libxml2 that can give me any pointers here. As far as I can tell the XCAP server code looks OK to me, and I believe the documents (attached) and my XCAP queries are correct as well.<BR>
<BR>
Thanks,<BR>
<BR>
Peter<BR>
