Hi Michael,
I took a look at this and was able to successfully stream parse the
feature collection. Here is the code:
GMLConfiguration configuration = new GMLConfiguration();
configuration.getProperties().add(Parser.Properties.PARSE_UNKNOWN_ELEMENTS);
InputStream xml = new URL("http://pisa007.....";).openStream();
StreamingParser parser = new StreamingParser(configuration, xml,
"//featureMember");
Feature f = null;
while( ( f = (Feature) parser.parse() ) != null ) {
//do something with feature
}
This relies on a recent fix to the parser, so make sure you are working
with recent snapshots of both gt2-xml-xsd and gt2-xml-gml2. The easiest
way to ensure you have a recent snapshot would be to depend on with via
a maven project, not sure if you can do that though.
I apologize for initially misdiagnosing your problem. You actually don't
want to use the property IGNORE_SCHEMA_LOCATION in this case since the
document correctly specifies the definition of the application schemas.
Please let me know if you have any more problems.
