Hi, 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 http://192.168.0.130:5060/xcap-root/pidf-manipulation/users/sip:111@mydomain/index~~/presence/tuple/note
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 % 5b@id='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. Any idea?
