AS3从外部XML将变量加载到Textfield中

Question

I have a php file which outputs an XML data and i also have a swf file coded with AS3 where i want to load the ouput of PHP in.

PHP Code:

 echo "<root>
           <Username>" . $xml1 . "</Username>
           <XMLNode2>" . $xml2 . "</XMLNode2>
            <XMLNode3>" . $xml3 . "</XMLNode3>
         </root>";

AS3 Code:

import flash.events.*;
import flash.net.URLLoader;
import flash.net.URLLoaderDataFormat;
import flash.net.URLRequest;
import flash.net.URLVariables;
import flash.xml.XMLDocument;

var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onLoaded);
loader.load(new URLRequest("playerData.php"));
var variables:URLVariables = new URLVariables();

function onLoaded(evt:Event):void
{
    var xDoc:XMLDocument = new XMLDocument();
    xDoc.ignoreWhite = true;
    loader.resultFormat = "e4x";
    var myXML:XML = loader.data as XML;
    xDoc.parseXML(myXML.toString());
    user_name.text = trace(xDoc.Username);
}

This is the error i get in AS3 code:

Access of possibly undefined property Username through a reference with static type flash.xml:XMLDocument.

Basically those TxtElements are dinamic text (like labels).

You can simply do :

var loader:URLLoader = new URLLoader();
    loader.addEventListener(Event.COMPLETE, onLoaded);
    loader.load(new URLRequest('playerData.php'));

function onLoaded(evt:Event):void
{   
    var myXML:XML = new XML(evt.target.data);
    trace(myXML.Username);                           // gives : the value of your php $xml1 var

    userField.text = (myXML.Username).toString();    // we don't need trace() to assing a value to a textfield

}
