[OpenLayers-Users] Adding Layers, updating the Layer Switcher

[Arnd Wippermann]

Hi,
 
Adding layers to a map you can see at the many examples. To remove a layer
you can use 

map.removeLayer(layer);

To add a WMS layer from a given url, is not so easy. You have to make a
GetCapability request, parse the response, build the layer declaration and
add the layer to the map. To get the GetCapability response, you have to use
a proxy script.

To get a WMS layer I have used some own code, but there should be something
in the OpenLayers library for parsing the GetCapability response.
