读取XML的代码:
stop();
var pictotal:Number;
var url:Array=new Array;
var surl:Array=new Array;
var myXML:XML = new XML();
var XML_URL:String = “list.xml”;
var myXMLURL:URLRequest = new URLRequest(XML_URL);
var myLoader:URLLoader = new URLLoader(myXMLURL);
myLoader.addEventListener(Event.COMPLETE, xmlLoaded);
myLoader.addEventListener(ProgressEvent.PROGRESS, xmlLoading);
myLoader.addEventListener(IOErrorEvent.IO_ERROR, xmlError);
function xmlLoaded(event:Event) {
var myXML:XML = XML(myLoader.data);
pictotal=myXML.img.length();
for (i=0; i
   url[i]=myXML.img[i].url;
   surl[i]=myXML.img[i].surl;
}
play();
}
function xmlLoading(event:ProgressEvent) {
loading_txt.text = “XML已加载”+Math.round ((event.bytesLoaded/event.bytesLoaded)*100)+”%”;
}
function xmlError(event:IOErrorEvent) {
trace(”XML加载失败”);
}
