ogr2ogr --version = GDAL 1.10.1, released 2013/08/26
python --version = Python 2.7.3
I have modified my script to get the field type
while feat is not None:
feat_defn = layer.GetLayerDefn()
field_defn =
feat_defn.GetFieldDefn(feat_defn.GetFieldIndex(attribut))
print field_defn.GetType()
if field_defn.GetType() == ogr.OFTReal:
print "%.4f" % feat.GetFieldAsDouble(attribut)
output.add(feat.GetFieldAsString(attribut))
feat = layer.GetNextFeature()
It detects that it is a real, But GetFieldAsDouble also truncate the value
at the comma

Python ogr GetFieldAsString problem
I'm trying to parse a GML and read all the values of an attribute.
Example
<gml:featureMember>
<ms:SMDVDP_STAT_METE fid="SMDVDP_STAT_METE.2153">
<ms:LONG_STAT>-64,2131</ms:LONG_STAT>
</ms:SMDVDP_STAT_METE>
</gml:featureMember>
DescribeFeatureType for this layer returns
<element name="LONG_STAT" minOccurs="0" type="double"/>
wfs_ds = ogr.Open(tmp_file.name) #tmp_file.name is the response of a WFS
getFeature request
layer = wfs_ds.GetLayerByName('SMDVDP_STAT_METE ')
feat = layer.GetNextFeature()
while feat is not None:
output.add(feat.GetFieldAsString('LONG_STAT'))
feat = layer.GetNextFeature()
(At runtime, the WFs, layer and attribute can be anything of any type. And
decimal separator, can be ',' or '.')
The problem is that feat.GetFieldAsString('LONG_STAT') truncate the string
to the comma
So instead of having -64,2131, I get -64 in the output
What is the appropriate way to get the value of an attribute?
thanks you!
