xml data binding flex web services
flex xml data binding using xml from a .net web service  
how to work with xml data using flex returned from a .net web service
flex and xml .net web services 

THE FIRST WEBSITE WAS PERFECT FOR TURNING A QUERY

RESULT(DATAGRID) INTO A USEABLE LIST IN FLEX

http://www.codeproject.com/KB/aspnet/FlexASPWebService.aspx

BUT i WANT THE NEXT STEP:

RETURNING XML DATA FROM A .NET WEB SERVICE INTO A FLEX WEB APPLICATION

HERE IS THE XML .NET 3.5  WEB SERVICE CODE (YES XML IS RETURNED)

    <WebMethod(Description:="Returns sample XML Data", EnableSession:=False)> _
    Public Function getSampleXmlData() As String
        Dim locStringBuild As New StringBuilder()
        locStringBuild.Append("<?xml version='1.0' encoding='utf-8'?>")
        locStringBuild.Append("<Data>")
        locStringBuild.Append("<Person>")
        locStringBuild.Append("<Name>WS-Ed Herrmann</Name>")
        locStringBuild.Append("<Location>WS-New Jersey</Location>")
        locStringBuild.Append("<Age>34</Age>")
        locStringBuild.Append("</Person>")
        locStringBuild.Append("<Person>")
        locStringBuild.Append("<Name>WS-Dan McWeeney</Name>")
        locStringBuild.Append("<Location>WS-New Jersey</Location>")
        locStringBuild.Append("<Age>27</Age>")
        locStringBuild.Append("</Person>")
        locStringBuild.Append("<Person>")
        locStringBuild.Append("<Name>WS-Matthias Zeller</Name>")
        locStringBuild.Append("<Location>WS-California</Location>")
        locStringBuild.Append("<Age>34</Age>")
        locStringBuild.Append("</Person>")
        locStringBuild.Append("</Data>")
        Return locStringBuild.ToString()
    End Function

HERE IS THE MXML CODE FOR THE FLEX APPLICATION

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" creationComplete="init()">

   private function xmlWSResult(event:ResultEvent):void{
    var myPeople:XML = new XML(event.result);
    myDataGrid.dataProvider = myPeople.Person;
     if (event.result != null){
      Alert.show("Event Result ----found");
      //build an array to store our totals for each location
      var locationArray:Array = new Array;
      for each (var node:XML in event.result ){
       Alert.show("Node hit");
      }
     }
     else {
      Alert.show("Event Result is null");
     }    
    //Alert.show("DATA RETRIEVED");
   } 

   private function xmlWSResult(event:ResultEvent):void{
    var myPeople:XML = new XML(event.result);
    myDataGrid.dataProvider = myPeople.Person;
     if (event.result != null){
      Alert.show("Event Result ----found");
      //build an array to store our totals for each location
      var locationArray:Array = new Array;
      for each (var node:XML in event.result ){
       Alert.show("Node hit");
      }
     }
     else {
      Alert.show("Event Result is null");
     }    
   } 

  <mx:WebService id="ws" wsdl="https://MYSAMPLESITE.COM?WSDL"
        fault="fault(event)">
   <mx:operation
    name="getSampleXmlData"
    resultFormat="object"
    result="xmlWSResult(event)"
    />   
  </mx:WebService>

   <mx:DataGrid x="10" y="42" width="490" height="237" id="myDataGrid">
    <mx:columns>
     <mx:DataGridColumn headerText="Name" dataField="Name"/>
     <mx:DataGridColumn headerText="Location" dataField="Location"/>
     <mx:DataGridColumn headerText="Age" dataField="Age"/>
    </mx:columns>
   </mx:DataGrid>
