[Geotools-devel] GML3 Parser Issue with QGIS generated data

[Bastian S. <sch...@un...>]

List,

we have a problem with the GML3 Parser (release 2.7.4):

Code:
----------
Configuration configuration = new GMLConfiguration();
configuration.getProperties().add(Parser.Properties.IGNORE_SCHEMA_LOCATION 
);
configuration.getProperties().add(Parser.Properties.PARSE_UNKNOWN_ELEMENTS);

org.geotools.xml.Parser parser = new org.geotools.xml.Parser(configuration);

Object parsedData =  parser.parse(new FileInputStream(file));
if(parsedData instanceof FeatureCollection){
       fc = (FeatureCollection) parsedData;
....
--------

We have data generated by QGIS as input. The created GML is a mess and 
not valid against the given (generic) gml schema nor are the namespaces 
correct, but the GML3 parser can figure out the geometries for Points 
but not for Polygons.

Why is that? What is wrong?
