Actionscript 3.0 :: Load XML From External Server?

I would like to load a xml-file from an external server (maps.google.com). My aim is to tell the user his coordinates, so I use googles Geocoding API. The problem however seems to be somewhere in accessing anything outside my own website. I tried the swf in Flash CS3 and it worked, I tried it on my website with a local xml-file with the same content as google would respond and it worked. So there must be something that suppresses the connection to another server. If I listen to the HTTPStatusEvent it's just "httpStatus: [HTTPStatusEvent type="httpStatus" bubbles=false cancelable=false eventPhase=2 status=0]", so I can't tell from the status where the mistake is (and according to the Flash Doc it always returns 0 except in IE, but it also does there).

If it help, the AS Code:

Code: Select allsuchen.addEventListener(MouseEvent.MOUSE_DOWN, suche); //searchbutton
ort.addEventListener(KeyboardEvent.KEY_UP, keyPressed); //textinput
function keyPressed(event:KeyboardEvent):void {

[Code]....
