You are going to need the XML schema that test.xml refers to.
Unlike shapefile there is no such thing as a "GML Format"; each GML file is
defined against an XML Schema that you provide. The Schema "extends" the GML
schema in order to reuse concepts like Geometry and Feature.
At the top of your test.xml file you should be able to see a reference to the
schema used to define the file?
I really recommend you look at the library test cases for examples of GML
parsing and encoding.
