解析XMLSocket返回值XML文档

今天学习XMLSocket，可是在拿到XML字符串数据后，不知该如何解析，JavaEye真是个好地方，终于找到了思路：

http://xiaoer-1982.iteye.com/blog/500333

 

首先由XML得到XMLList，然后构造出XMLListCollection，最后得到Array，最后构造ArrayCollection。

 

原始XML字符串：

<response>

   <resp time="" no="" lat="" lng="" />

   <resp ............ />

</response>

 

var response:XML = new XML(event.data);
 
 var xmlListColl:XMLListCollection = new XMLListCollection();
 xmlListColl.source = response.elements("resp");
 
 var arr:Array = xmlListColl.toArray();
 
 var arrColl:ArrayCollection = new ArrayCollection();
 arrColl.source = arr;
 
 for(var i:int = 0; i < arrColl.length; i++)
 {
  var resp:Object = arrColl.getItemAt(i);
  result.text += resp.@time + ":" + resp.@no + "[" + resp.@lat + ", " + resp.@lng + "]\n";
  txtiptName.text = resp.@no;
  this.onChange(1);
 }

 

将整个AS文件发上来：
