[OpenLayers-Users] changing KML-URL with AJAX

[Tim Alder]

Hello,
I'm a openlayers-newbie. I used successfully the Openlayers KML Example[1].
I think it looks for my first experiment really nice[2], thanks to the 
openlayers-developers.

Now, I want to chance the kml-URL from outside the map with help of a 
javascript function like "change(newurl)"
How would this function look alike? The object-paths looks too complex 
for me. Who can help?
