引用xml内容，换行操作的方法1

import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.events.Event;

var str:String;
var myList:XMLList
var pattern:RegExp = /\$/gi;//以$作为换行的判断点
var xmlloader:URLLoader = new URLLoader(new URLRequest("images.xml"));
var myxml:XML;
xmlloader.addEventListener(Event.COMPLETE,handleLoaded);
function handleLoaded(e:Event):void{
    myxml = new XML(xmlloader.data);
    myList = myxml.img;
    str = myList[0].@desc;
    abc.text = str.replace(pattern,"\n");
}
