How to call one Main MXML from another main MXML file and pass values between them?

Question

Hi,
I am trying to populate a datagrid from a XML file ,which I have done successful
I am able to get data out of the datagrid on clicking on any element
Now when I click on any element in datagrid I want call a new mxml file which is also have Aplication tag and I want to pass that value of clicked element to it
This is the code I am using for getting data from XML into data grid in 1st MXML file and the XML file used.
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
                xmlns:s="library://ns.adobe.com/flex/spark"
                 xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"  initialize="exp.send()">
     <fx:Declarations>
         <s:HTTPService id="exp" url="expLab1.xml" result="
resultHandlerQuestionBar(event)"/>
     </fx:Declarations>
     <s:Panel x="74" y="218" width="485" height="333" title="Work On Configured Experiments" id="p1" fontSize="14" chromeColor="#9BFDAB" dropShadowVisible="false" contentBackgroundColor="#E4EEE6" contentBackgroundAlpha="1.0" backgroundColor="#67B6AC" textAlign="left">
          <mx:DataGrid  x="35" y="33" width="338" height="88" dataProvider="{experimentdetails}" chromeColor="#FCFCFC" contentBackgroundColor="#FFFFFF" selectionColor="#FAFBFD" rollOverColor="#FCFDFF" focusColor="#FCFDFD" itemClick="onItemClick( event );">
              <mx:columns>
                 <mx:DataGridColumn id="j1" dataField="experimentName" headerText="" itemRenderer="jaya">
                 </mx:DataGridColumn>
              </mx:columns>
         </mx:DataGrid>
     </s:Panel>
     <fx:Script>
         <![CDATA[
             import mx.collections.ArrayCollection;
             import mx.controls.Alert;
              import mx.events.FlexEvent;
             import mx.events.ListEvent;
             import mx.rpc.events.ResultEvent;
             [Bindable]
             private var workbenchname:ArrayCollection;
              //private var a:String;
             private function resultHandlerQuestionBar(event:ResultEvent):void
                experimentdetails=event.result.List.experimentList.experiment;  
             [Bindable]
             private var experimentdetails:ArrayCollection;
              private var alert:Alert;
private var data:String;
             private function onItemClick( e:ListEvent ):void {
   data= experimentdetails.getItemAt(e.rowIndex).experimentName.toString();
                alert=Alert.show(experimentdetails.getItemAt(e.rowIndex).experimentName.toString());
         ]]>
     </fx:Script>
</s:Application>
and the xml file is:
<?xml version="1.0" encoding="UTF-8"?>
<List>
   <workbench>Basic Movement</workbench>
     <experimentList>
       <experiment>
         <experimentName>Distance with varying time</experimentName>
         <Rating>2</Rating>
         <expNO>1</expNO>
       </experiment>
       <experiment>
         <experimentName>Distance with Constant time</experimentName>
         <Rating>1</Rating>
         <expNO>2</expNO>
       </experiment>
       <experiment>
         <experimentName>Time taken while decelerating</experimentName>
         <Rating>3</Rating>
         <expNO>3</expNO>
       </experiment>
      </experimentList> 
</List>
Now the code for 2nd MXML is as follows
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
                     xmlns:s="library://ns.adobe.com/flex/spark"
                     xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
      <fx:Declarations>
            <!-- Place non-visual elements (e.g., services, value objects) here -->
      </fx:Declarations>
      <s:Label text="lable1" >
      </s:Label>
</s:Application>
