I could use a hand figuring out how to access this XML data with e4x
I'm not having alot of success so far

Code:

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

PHP Code:

---

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.

Reading toward digging out the yweather namespace...
