I want to convert my gml file to shapefiles. But our gml files was created by custom gml schema. We have their application schema, xsd. But i don't know how to put this schema path on command prompt or python ide. I downloaded fwtools, ogr2ogr main python code but i don't know to use. Do you know how?
