I try to suggest you something, but I hope not to give a trivial
suggestion to you...
Are you sure that you call MediaStation.getXMLContent() after the
callback returns? For what I can read in your code, you send the
callback in the try / catch block, then the next statement that is
executed is "return MediaStation.result". So you may not have finished
the callback execution at that point. Anyway this is a way of using a
getter function in conjunction with a request that I have never seen before.
