[Flashcoders] using a class to load data

[Allandt Bik-Elliott (Receptacle)]

hi guys

i am trying to set up a class to handle my xml (will be instantiated  
for each xml file) but i'm running into a slight problem

here is the class so far:

CODE
package
{
        //package imports
        import flash.events.*;
        import flash.net.*;
        
        internal class XMLLoader
        {
                // class variable declarations
                private var xmlDoc:XML;
                private var xmlURL:String;
                private var xmlLoader:URLLoader;
                
                public function get doc():XML {return xmlDoc;}
                
                // constructor
                public function XMLLoader(url:String)
                {
                        xmlURL = url;
                        var urlRequest:URLRequest = new URLRequest(xmlURL);
                        xmlLoader = new URLLoader();
                        xmlLoader.addEventListener(Event.COMPLETE, 
completeListener);
                        xmlLoader.load(urlRequest);
                }
                
                private function completeListener(e:Event):void
                {
                        xmlDoc = new XML(xmlLoader.data);
                }
        }
}
/CODE

the problem is with timing - from within the XMLLoader() Class i can  
wait for the COMPLETE event to reference the xmlDoc but how would i  
do that from an instance of the class?

for instance if i do the following from my main class i get a null  
object error because it doesn't wait for the data to be loaded before  
trying to read it:

CODE
var xmlurl:String = "path/to/xml.xml";
var xmlDoc:XMLLoader = new XMLLoader(xmlurl);
xmlDoc = xmlLoader.doc;
trace (xmlDoc.toXMLString());
/CODE

this would equally apply to an image loader, i guess

thanks in advance
a
