Replace XML is not working

[indiramm]

Hi,
I'm trying to load some content into flash from an XML rss feed.
I took the original code from gotoandlearn, and all I added was some buttons
to make this content change.
that is, when I click on a button, the xml has to be replaced for another one.
It works except that instead of replacing the content, it ADDs to the XML
list, everytime I click on the buttons.
I tried removing children but it doesn't work, cause it leaves no place to put
the new content.
HAve to say I'm kinda lost :)
thanks a lot!!!

Code:

import flash.display.Loader;
import flash.net.URLRequestMethod;
import flash.net.URLLoader;

import flash.display.LoaderInfo;

var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onLoaded);



lb.addEventListener(Event.CHANGE, itemChange);

function itemChange(e:Event):void
{
ta.text = lb.selectedItem.data;
}



var xml:XML;
var arr:Array = new Array();
var il:XMLList;


function onLoaded(e:Event):void
{

xml = new XML(e.target.data);
il = xml.channel.item;
for(var i:uint=0; i<il.length(); i++)
{
lb.addItem({data:il.description.text()[i],
label:il.title.text()[i]});
}
}


loader.load(new URLRequest("http://localhost/indira/category/txt/?feed=rss"));



this.bt_foto.addEventListener(MouseEvent.CLICK,Cli cFoto);

function ClicFoto(e:Event):void
{
xml = new XML
//il = 0;

loader.load(new URLRequest("http://localhost/indira/category/foto/?feed=rss"));
//il.removeItem();
//il = xml.channel.item;
//delete(xml);



trace(lb.numChildren);
}

this.bt_web.addEventListener(MouseEvent.CLICK,onCl ickweb);

function onClickweb(e:Event):void
{
trace(loader.data);

loader.load(new
URLRequest("http://localhost/indira/category/netweb/?feed=rss"));
}

Finally, it was pretty easy, at least now that it works:

I just had to remove all:

lb.removeAll();
