thanks jason - i've done this and it's working, i just wanted you to
take a look to make sure i've not done it stupidly
CODE
package
{
//package imports
import flash.events.*;
import flash.net.*;
internal class XMLLoader extends EventDispatcher
{
// class variable declarations
private var xmlDoc:XML;
private var xmlURL:String;
private var xmlLoader:URLLoader;
public static const COMPLETE:String = "complete";
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);
dispatchEvent(new Event(XMLLoader.COMPLETE));
}
}
}
/CODE
and the function call is
CODE
private var xmlDoc:XML;
private var xmlurl:String;
private var xmlLoader:XMLLoader;
// call to initialiseXML() made in constructor
private function initialiseXML():void
{
xmlLoader = new XMLLoader(xmlurl);
xmlLoader.addEventListener(Event.COMPLETE, completeListener);
}
private function completeListener(e:Event):void
{
xmlDoc = xmlLoader.doc;
trace (xmlDoc.toXMLString()); //traces xml correctly
}
/CODE

Have your XMLLoader class extend EventDispatcher and have your
XMLLoader
class dispatch an event when the load is complete. Wherever your
instance of the class is declared, add an event listener to the
instance
and write a function handler. if you need assistance with setting that
up, write back, it's pretty simple.

Subject: [Flashcoders] using a class to load data
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
