HTTPService e4x object

对于<mx:HTTPService resultFormat="object"/>，<UnderlyingRIC>123E45678</UnderlyingRIC>会解析为Number,导致界面上出现“Infinite”

使用resultFormat="e4x"来解决上述问题

          <mx:HTTPService id="KDBUnderlyingRICList" url="{myStrings.URLAddress + '.xml?UnderlyingRICList'}" 
          result="myFunctions.dataHandleUnderlyingRICList(event)" resultFormat="e4x"/>

          static public function dataHandleUnderlyingRICList(event:ResultEvent):void{
             myStrings.UnderlyingRICList = handleUnderlyingRIC(event.result);
          }
           //利用正则查找<UnderlyingRIC>123E45678</UnderlyingRIC>,转为<UnderlyingRIC>'123E45678</UnderlyingRIC>用SimpleXMLDecoder转成对象，在对象中再去掉'           
           static public function handleUnderlyingRIC(obj:Object):ArrayCollection{
            var xml:String=XML(obj).toString();
            var x:String=xml.replace(/(<UnderlyingRIC>)([^<>].*)(<\/UnderlyingRIC>)/g,"$1'$2$3");
            var decoder:SimpleXMLDecoder=new SimpleXMLDecoder(true);
            var obj1:Object=decoder.decodeXML(new XMLDocument(x));
            var ac:ArrayCollection=obj1.R.r as ArrayCollection;
            for each(var obj:Object in ac){
                obj.UnderlyingRIC=obj.UnderlyingRIC.toString().replace("'","");
            }
            return ac;
           }

下面的方法转为xml Object,不过要注意科学记数法E

      public function covertXmlToArray(xml:XML):ArrayCollection{
         return  new ArrayCollection(new XMLListCollection(xml.elements()).toArray());
      }
