using 2 different xml scripts

[maroccano1]

i would like to use 2 different xml scripts, one loads automatically and one loads when a button is pressed. however when i run the application the two xml scripts merge together???? i would like one to replace the other.

var xml:XML;


function onLoaded(e:Event):void
{
	

	
	xml = new XML(e.target.data);
	trace(xml);
	
	ilist = xml.item;

for(var i:uint=0;  i<ilist.length(); i++)
	{
		lbox.addItem({data:ilist.link.text()[i], data:ilist.path.text()[i],
					 label:ilist.title.text()[i]});
		
	}

}


 

 
on_auction.addEventListener(MouseEvent.CLICK, auctionlist);

	function auctionlist(e:Event):void
	{
		
		loader.load(new URLRequest("http://localhost/playlista_xml.php?u=12345"));
	}
			
//loader.load(new URLRequest("http://localhost/playlist.php?u="+valueStr)); 
loader.load(new URLRequest("http://localhost/playlist_xml.php?u=maroccano1"));

You could delete the variable before reloading.

delete lbox;
