I am trying to run a clip between an extent and a shapefile, then iterate through the resulting features to determine the one with the largest overlap (aka the feature with the largest area after the clip). After running clip:

ogr2ogr -clipsrc 23.894 42.327 24.89 42.769 -f "GML" -select "name" /path/to/tempOut /path/to/input.shp

I can iterate through the features and get the "name" of each feature like this:

from xml.dom import minidom

xml      = minidom.parse(tempOut)

features = xml.getElementsByTagName('gml:featureMember')



for feature in features:

    name = str(feature.getElementsByTagName('ogr:name')[0].firstChild.data)

I have been messing around trying to get an object that I could use in:

ogr.CreateGeometryFromGML() 

To then hopefully obtain the area of each feature (so I can determine which one overlaps with the extent provided the most), but I can't figure it out. Surely I'm missing something simple?

python gdal ogr2ogr
