as 3读取xml实现代码

as3对xml的操作实在是太方便了(e4x ecmascript for xml 没错.就是ecmascript 如果js比较好的同学对这个也很熟悉吧)..

package
{
 import flash.display.*;
 import flash.text.*;
 import flash.xml.*;
 import flash.net.*;
 import flash.events.event;
 
 public class classsubfeed extends sprite
 {
  var temp:textfield; 
  var myxmlurl:urlrequest;
  var myloader:urlloader;
  var xmlurl:string;
  var xmlcontent:xml;
 
  public function classsubfeed()
  {
   temp = new textfield();
   temp.x = 10;
   temp.y = 10;
   temp.width = 530;
   temp.height = 350;
   temp.border = true;
   temp.bordercolor = 0x669900;
   temp.multiline = true;
   temp.htmltext = "loading.....";
   addchild(temp);
 
   // xml地址
   xmlurl = "http://www.111cn.net/xml/5230.xml";
   this.loadxml(xmlurl);
  }
 
  private function loadxml(xmlurl:string):void
  {
   myxmlurl = new urlrequest(xmlurl);
   myloader = new urlloader(myxmlurl);
   myloader.addeventlistener(event.complete, onloaded);
  }
 
  private function onloaded(event):void
  {
   xmlcontent = xml(myloader.data);
   temp.htmltext = "已经读取feed,正在准备.....";
   this.parsedata(xmlcontent);
  }
 
  private function parsedata(xmlcontent:xml):void
  {
   var rrstitle:string = xmlcontent.channel.title;
   var rrslink:string = xmlcontent.channel.link;
   temp.htmltext = "

" + rrstitle + "

";
 
   for each(var item:xml in xmlcontent..item)
   {
    var itemtitle:string = item.title.tostring();
    var itemlink:string = item.link.tostring();
    temp.htmltext += "

" + itemtitle + "

";
   }
  }
 }
}

实例二，读取外部xml 文件
