Got it. But what if it gets a bit more difficult than that? :)
I've an xml document where the namespace for some elements changes, like
this:
<?xml version="1.0" encoding="utf-8"?>
<presence xmlns="urn:ietf:params:xml:ns:pidf" entity="sip:f...@mydomain.com">
<tuple id="86ae65b7-42de-4399-b635-295caad13aac">
<status>
<basic>none</basic>
<geopriv xmlns="urn:ietf:params:xml:ns:pidf:geopriv10">
<location-info>
<location xmlns="http://www.opengis.net/gml";>
[snip]
As you can see, the "geopriv" element changes the namespace from "pidf"
to "pidf:geopriv10". Even giving the full namespace
(".../urn:ietf:params:xml:ns:pidf:geopriv10:geopriv") to capture the
"geopriv" element results in
ERROR: presence_xml [pv_xml.c:310]: unable to evaluate xpath expression
[/pidf:presence/pidf:tuple/pidf:status/urn:ietf:params:xml:ns:pidf:geopriv10:geopriv/83]
Any ideas are highly appreciated :)
