OK, very nice. Today I read a lot about it and it seems I could
realize it on this way. My idea is now:
I create two classes: xmlMulticastSocket and
xmlMulticastSocketListener. If the xmlMulticastSocketListener (runs in
a second thread) gets the xml-file completely it should fire an
nsIDOMDataContainerEvent. This Event would be handled by a JavaScript
function (So the multicastSocket is also created with javascript). My
Question is: How "fire" I the event in c++? I think to make an
instance of an event isn't enough, is it?

It would be nice to help me again... Thanks a lot!
