by now creating groundoverlays and simple placemarks out of a kml file
works fine, but it doesn't work for polygons. Again I compared my code
to the one from the KMLParser example, but I could not find any
difference (neither in the kml nor in the code).
The placemark from the kml below is recognized as a placemark, but the
following check if it is a polygon fails and therefore always the code
in the else-part is executed. Do you have any idea what the problem
could be?
KML:
-----------------
<Placemark>
<name>poly</name>
<styleUrl>#msn_ylw-pushpin</styleUrl>
<Polygon>
<tessellate>1</tessellate>
<outerBoundaryIs>
<LinearRing>
<coordinates>8.07250406876639,40.97693126116689,0

var placemark:Placemark =
com.google.maps.extras.xmlparsers.kml.Placemark::Placemark(feature);

var point: com.google.maps.extras.xmlparsers.kml.Point::Point =

var lineString:LineString = LineString(placemark.geometry);
obj.mapObject = new Polyline(getCoordinatesLatLngs
(lineString.coordinates));
