[SR-Users] parse XML nested name-spaces

[Artur Hovsepyan]

it still fails, i have tried handful scenarios, but still failing:
    454 modparam("xmlops", "xml_ns", "rpid=urn:ietf:params:xml:ns:pidf:rpid")
    455 modparam("xmlops", "xml_ns", "pidf=urn:ietf:params:xml:ns:pidf")
    456 modparam("xmlops", "xml_ns", "gp=urn:ietf:params:xml:ns:pidf:geopriv10")
    457 modparam("xmlops", "xml_ns", "dm=urn:ietf:params:xml:ns:pidf:data-model")
    458 modparam("xmlops", "xml_ns", "gs=http://www.opengis.net/pidflo/1.0")

with the text() function, i am getting error:
ERROR: <core> [core/pvapi.c:176]: pv_locate_name(): non-closing inner-name parenthesis [$xml(x=>xpath:/pidf:presence/dm:device/gp:geopriv/gp:location-info/gs:Circle/gml:pos/text()]
without text, i am getting this:
ERROR: xmlops [pv_xml.c:308]: pv_get_xml(): unable to evaluate xpath expression [/pidf:presence/dm:device/gp:geopriv/gp:location-info/gs:Circle/gml:pos/70]

i am still stuck.

iirc, to get the text between tags, you have to use text() function of xpath (should be in the xpath specs) -- I guess you have to use:
 
$xml(x=>xpath:/pidf:presence/dm:device/gp:geopriv/gp:location-info/gs:Circle/gml:pos/text())
 
Cheers,

 good evening everyone, 
  can you please help how to parse following XML body and get the "<gml:pos>31.204359 -44.512358</gml:pos>" in a variable? 
  
   <?xml version="1.0"?>
 <presence xmlns="urn:ietf:params:xml:ns:pidf" xmlns:dm="urn:ietf:params:xml:ns:pidf:data-model" xmlns:gp="urn:ietf:params:xml:ns:pidf:geopriv10" xmlns:gml="http://www.opengis.net/gml" xmlns:gs="http://www.opengis.net/pidflo/1.0" xmlns:con="urn:ietf:params:xml:ns:geopriv:conf" entity="sip:+6478897789 at ims.mnc0xx.mccxxx.3gppnetwork.org">
 <dm:device id="Wifi">
 <gp:geopriv>
 <gp:location-info>
 <gs:Circle srsName="urn:ogc:def:crs:EPSG::5524">
 <gml:pos>31.204359 -44.512358</gml:pos>
 <gs:radius uom="urn:ogc:def:uom:EPSG::8190">10.578000</gs:radius>
 </gs:Circle>
 <con:confidence pdf="normal">92</con:confidence>
 </gp:location-info>
 <gp:method>DBH_HELO</gp:method>
 <gp:usage-rules/>
 </gp:geopriv>
<dm:timestamp>2022-04-05T19:16:34Z</dm:timestamp>
 </dm:device>
 </presence> 
  i tried few variants:
  
   xinfo("GML_LOC:$xml(x=>xpath:/pidf:presence/pidf:dm:device/pidf:gp:geopriv/pidf:gp:location-info/pidf:gs:Circle/pidf:gml:pos)\n")
 xinfo("GML_LOC:$xml(x=>xpath:/pidf:presence/pidf:dm\:device/pidf:gp\:geopriv/pidf:gp\:location-info/pidf:gs\:Circle/pidf:gml\:pos)\n");
 xinfo("GML_LOC:$xml(x=>xpath:/pidf:presence/pidf:dm:device/pidf:gp:geopriv/pidf:gp:location-info/pidf:gs:Circle/pidf:gml:pos)\n");
 xinfo("GML_LOC:$xml(x=>xpath:/pidf:presence/dm:device/gp:geopriv/gp:location-info/gs:Circle/gml:pos)\n"); 
  and end up with error "unable to evaluate xpath expression": 
  ERROR: xmlops [pv_xml.c:308]: pv_get_xml(): unable to evaluate xpath expression[/pidf:presence/dm:device/gp:geopriv/gp:location-info/gs:Circle/gml:pos/70]
    
  thanks in advance, Art
