Parsing url parameters in a String

Question

I am using the example code in flash. I want a single variable and not the whole text. I have a dynamic textfield called OUTPUT on the stage.

var fl_TextLoader:URLLoader = new URLLoader();
var fl_TextURLRequest:URLRequest = new URLRequest("http://www.testing.com/Christmas.txt");

fl_TextLoader.addEventListener(Event.COMPLETE, fl_CompleteHandler);

function fl_CompleteHandler(event:Event):void
{
    var textData:String = new String(fl_TextLoader.data);
    OUTPUT.text = textData;
}

fl_TextLoader.load(fl_TextURLRequest);

The Christmas text file contents:

Var1=Jesus&Var2=Mary&Var3=Christmas

The OUTPUT comes out with the whole string. How do I get the url parameter values separately?

Like OUTPUT.text = textData.Var1; (<--- But this does not work.)

The .data property is just a string, the raw data returned by the HTTP call, so you will have to parse the variable-value pairs, either using simple .split() on the strings or using the URLVariables object, that can do the parsing for you:
