How to Add a KML from My Google Maps to OpenLayers?

Question

I would like to add this kml-link from Google Maps to an OpenLayers instance.

The following code is not working:

var layer = new OpenLayers.Layer.GML("KML", "https://maps.google.de/maps/ms?authuser=0& vps=2&hl=de&ie=UTF8&msa=0&output=kml&msid=203149634091768565111.0004cf65c9b03cc8ae76c", 
{
format: OpenLayers.Format.KML,
formatOptions: {
'extractStyles': true
}
});

Thanks alot for any ideas!

Answer 1

You should put the kml on the server and link to the file. Like this:

var layer = new OpenLayers.Layer.GML("KML", "kml/lines.kml", {
   format: OpenLayers.Format.KML
})
map.addLayer(layer);
