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?

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
