flex reading data from XML url

This is how the Config.xml looks like:
  <?xml version="1.0" ?>
  <config channelName="zee" bgColor="0xcc0066" 
gridNumRows="3" gridNumCols="3" />

This example shows how to read the attributes of
an XML node.



<mx:HTTPService id="readConfig"
      url="Config.xml" resultFormat="xml"
      result="showClips(event)"/>
  <mx:script>
      <![CDATA[
      import mx.rpc.events.ResultEvent;

      [Bindable]

      [Bindable]
      private var configParams:XML;

      private function showClips(event:ResultEvent):void {
          configParams = (XML)(event.result);
          mainGrid.rowCount = (int)((int)(configParams.@gridNumRows)-(int)('0'));
          mainGrid.columnCount = (int)((int)(configParams.@gridNumCols)-(int)('0'));
          cnLabel.text = configParams.@channelName;
      }
