 Most of the time we are facing difficulties in using the xml in data transfer object. So here is my simple solution for this problem. We can easily conver the xml into object with the use of simpleXMLDecoder. The only thing we have to do is just convert the xmlString into XMLDocument and pass this xmlDocument into the simpleXMLDecoder.

Here is how its works:    
 private function xmlConverter(xml:XML):ArrayCollection{                 
      var xmlStr:String = xml.toString();
      var xmlDoc:XMLDocument = new XMLDocument(xmlStr);
      var decoder:SimpleXMLDecoder = new SimpleXMLDecoder(true);
      var resultObj:Object = decoder.decodeXML(xmlDoc);
      var ac:ArrayCollectin = new ArrayCollection();
      ac =  resultObj.Items.Item;
      return ac;
}

Comparison with NaN

 Any comparison with NaN is always false:  

We can match the default value with the related data type. But in Number data type NaN(Not A Number) is the default value. But matching the NaN with Default Number value rise the “error – Ilogical comparison with NaN”. 

  //NaN is the default value of the Number Data Type 
   private var myNumber:Number;
   private function checkType():void{
   //if(myNumber==NaN){   outPut //error – Ilogical comparison with NaN
   if(isNaN(myNumber)){   
   trace(myNumber) //NaN
   }
}
