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:pos31.204359 -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:pos31.204359 -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:methodDBH_HELO</gp:method> gp:usage-rules/ </gp:geopriv> dm:timestamp2022-04-05T19:16:34Z</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
