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())

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@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: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,
