AS3 :: Flash - Add <hr/> Tag And Utm Tags?

first, I need to show an <hr/> tag after the description, its an rss widget so need to seperate with each rss post with a border or hr. Its not possible to make it manually because its came from xml. I'll give you the existing script with me.

second, I need to add utm tag after the urls to trace the clicks, this is actually I need to add after the links 'utm_source=rsswidget', you'll get an idea by seeing the script below

var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onLoaded);
var xml:XML;
function onLoaded(e:Event):void

[Code]....
