Ok so I figured it out mostly..... Here is a great example of why E4X is very useful in parsing XML data....

put a html text field on the stage and add the following code in AS3


var loc="30062";//Default Location

var xmlLoader:URLLoader = new URLLoader();
var xmlData:XML = new XML();

xmlLoader.addEventListener(Event.COMPLETE, LoadXML);

xmlLoader.load(new URLRequest("http://weather.yahooapis.com/forecastrss?p="+loc));

function LoadXML(e:Event):void {
xmlData = new XML(e.target.data);
txt2.htmlText=xmlData.channel.item.title;
txt2.htmlText+=xmlData.channel.item.description;
debug.text=txt2.htmlText
}

Very cool. E4X is good ju-ju.
