[OpenLayers-Users] parsing a GML file into different layers

[Alex Brandsen]

Hi Arnd,

thanks for your reply, this seems like it should work. I've been trying it
out, but can't get it to work.. What should go in the brackets after 'GML',
and where does 'response' come from? Sorry if these are really basic
questions, but I don't have much experience in JS or OL...

Thanks again,

Alex.
