AW: [OpenLayers-Users] Problems loading GML with hole

[Arnd Wippermann]

Hi,

The exported gml describes a multipolygon with two polygons and not a
polygon with a hole.

A polygon with a hole therefor is described by an outer and innerBoundary
for this polygon.

<cit:Feature gml:fid="0">

Betreff: [OpenLayers-Users] Problems loading GML with hole

Hi list,
 
I'm facing some problems while loading a GML file that has a geometry with a
hole. The GML is exported from gvSIG. Then I try to load it with Openlayers,
but I can't get the geometry drawn with the hole. I get two geometries
drawn. I attach the gml to the email. I'm using OpenLayers 2.9.
 
My parsing code
 
	var theParser = new OpenLayers.Format.GML();
      theParser.internalProjection = null;
      theParser.externalProjection = null;
      theParser.extractStyles = false;
      theParser.extractAttributes = true;
 
      var features = theParser.read(req);
 
Any ideas?

Thanks in advance.
 
Un saludo,
