problem with istsos demo server

[lucadelu]

Running this command

python v.in.sos.py url=http://istsos.org/istsos/demo? offering=LOCARNO observed_properties='urn:ogc:def:parameter:x-istsos:1.0:meteo:air:temperature' response_format='text/xml;subtype="om/1.0.0"' output=locarno_temp event_time="2014-06-03T15:00:00+01:00/2014-06-03T18:00:00+01:00"

I got

Traceback (most recent call last):
  File "v.in.sos.py", line 266, in <module>
    main()
  File "v.in.sos.py", line 156, in main
    parsed_obs.update({property: xml2geojson(obs, property)})
  File "/home/lucadelu/github/GRASS-GIS-SOS-tools/format_conversions/xml2geojson.py", line 42, in xml2geojson
    for values in item.text.split(blockSeparator):

It's strange. I have tried to save the xml from parsed_obs and I got output.txt and there are no observed values.

The problem is in time. When I try it without defining time or with v.in.sos url=http://istsos.org/istsos/demo? offering=LOCARNO observed_properties='urn:ogc:def:parameter:x-istsos:1.0:meteo:air:temperature' response_format='text/xml;subtype="om/1.0.0"' output=locarno_temp event_time="2014-06-03T13:00:00+01:00/2014-06-03T18:00:00+01:00" --overwrite it works (there are observed values).

Ok, if there are no observed values it cannot return that error but something like "There is no data, could you change the time parameter, observed properties, procedures or offerings"

[lucadelu]

Now it return

you should use grass.warning/grass.errors (probably better the second one, so the process will be stopped)

[pesekon2]

Yes, it's caused by removing new (output vector). I have replaced it now with error in this commit but I'm not sure how clear it is to raise an error without closing and removing the output.
