And IMPORTANT: do not initialize/set it when you declare it. You can
only initialize instance variables to simple values. Set its value
inside the function.
public var _myLoader:URLLoader; //declare this outside of a function.
The leading underscore is just a convention
public var _myXML:XML; //this too
...
private function initUrlLoader():void {
var XML_URL:String ="http://whatever <http://whatever/> ";
var myXMLURL:URLRequest = new URLRequest(XML_URL);
_myLoader = new URLLoader(myXMLURL);
_myLoader.addEventListener("complete", xmlLoaded);
...
}
function xmlLoaded(event:Event):void
{
_myXML = XML(_myLoader.data);
trace("Data loaded.");
}

Declare the variable in the "instance" scope, that is, not inside a
function. That will make it available anywhere within the class
instance. In non-OO terms, you might call it a "global" variable, but
it is not really global, only global to the class instance, hence the
term "instance" variable.

Do you mean something like this:
public var myLoader:URLLoader = new URLLoader(myXMLURL);
I tried it but it didn't work... What do you mean by instance variable?
