Question

I’m trying to return XML from an event complete back to the main function, but can’t figure out how to do it.

Here’s the functions I’m calling:

Main File:

public var mySendAndLoad:SendAndLoad = new SendAndLoad(); 

mySendAndLoad.sendData(url,variables)

The mySendAndLoad class:

package 
{

    import flash.events.*;
    import flash.net.*;
    import flash.xml.XMLDocument;

    public class SendAndLoad
    {
        public var xml:XML = new XML();
        public var xmlList:XMLList;

        public function SendAndLoad()
        {
        }
        public function sendData(url:String, _vars:URLVariables):String
        {
            var request:URLRequest = new URLRequest(url);
            var loader:URLLoader = new URLLoader();
            loader.dataFormat = URLLoaderDataFormat.TEXT;
            request.data = _vars;
            request.method = URLRequestMethod.POST;
            loader.addEventListener(Event.COMPLETE, handleComplete);
            loader.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
            loader.load(request);
        }
        private function handleComplete(event:Event):String
        {
            var loader:URLLoader = URLLoader(event.target);
            xml = XML(loader.data);
            xmlList = xml.children();
            return(xmlList[1]);
        }
        private function onIOError(event:IOErrorEvent):void
        {
            trace("Error loading URL.");
        }
    }
}

What I want to happen is have the xmlList come back to the main file. But since it isn’t in the event I called (sendData) it doesn’t get brought back.

Any ideas?

package 
{

import flash.events.*;
import flash.net.*;
import flash.xml.XMLDocument;

//THIS CLASS EXTENDS EVENTDISPATCHER SO IT CAN DISPATCH EVENTS
public class SendAndLoad extends EventDispatcher
{
    public var xml:XML = new XML();
    public var xmlList:XMLList;

    public function SendAndLoad()
    {
        super(null);
    }
    public function sendData(url:String, _vars:URLVariables):void
    {
        var request:URLRequest = new URLRequest(url);
        var loader:URLLoader = new URLLoader();
        loader.dataFormat = URLLoaderDataFormat.TEXT;
        request.data = _vars;
        request.method = URLRequestMethod.POST;
        loader.addEventListener(Event.COMPLETE, handleComplete);
        loader.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
        loader.load(request);
    }
    private function handleComplete(event:Event):void
    {
        var loader:URLLoader = URLLoader(event.target);
        xml = XML(loader.data);
        xmlList = xml.children();


        //NEW CODE
        var evt:Event=new Event(Event.COMPLETE);
        dispatchEvent(evt);
        //return(xmlList[1]);
    }
    private function onIOError(event:IOErrorEvent):void
    {
        trace("Error loading URL.");
    }
}

}

and in the main file

public var mySendAndLoad:SendAndLoad = new SendAndLoad(); 
mySendAndLoad.addEventListener(Event.COMPLETE, xmlLoadCompleted);
mySendAndLoad.sendData(url,variables)

private function xmlLoadCompleted(e:Event):void {
    var childToUse:XML=mySendAndLoad.xmlList[1];
    //whatever else you want to do 
}
