Flex Fix: Load New XML In SWF?

My AS3 swf loads xml like this: var xmlLoader:URLLoader = new URLLoader(); var xmlData = new XML(); [login to view URL]([login to view URL], LoadXML); [login to view URL](new URLRequest("mix_quiz.xml")); //[login to view URL](new URLRequest("audio_quiz.xml")); //[login to view URL](new URLRequest("xml/image_quiz.xml")); //[login to view URL](new URLRequest("xml/12_quiz.xml")); function LoadXML(e:Event):void { xmlData = new XML([login to view URL]); ParseXML(xmlData); } How can can change this XML file, by let's say clicking on a button in Flex? My SWFLoader: Should be a quick fix for a guru!!
