[OpenLayers-Users] using external styles with OpenLayers.Format.KML

[K Clair]

 hi,

 i'm trying to move my kml styles to an external document for use with 
 openlayers. the styles work when they are included directly in the kml 
 file.

 at first i thought i could use straight kml for this with the styleUrl 
 tag:

 <styleUrl>http://localhost/map.kml#myIcon</styleUrl>

 however when i try to do that, the map.kml file never gets requested, 
 and the markers don't show up. i've verified that the styleUrl url 
 works.

 i'm loading my kml using:

 new OpenLayers.Layer.GML('Name', 'kml_path', {
   format: OpenLayers.Format.KML,
     formatOptions: {
       extractStyles: true,
       extractAttributes: true
     },
     projection: map.displayProjection
 });

 there are some tantalizing options called 'styles' and 'styleBaseUrl' 
 in the OpenLayers.Format.KML API, but i cannot find any documentation 
 about what they are for or how to use them. does anyone have any 
 experience with these?

 thanks,
 kristina
