How to Edit a XML data file from AS3 class...

Question

  Hi...
             I need to edit an XML data file I have at the exit of application.... I have a demo code which is not working....
This is the code :
public function UpdateData():void
               trace("Closing....");
               var FileData:XML=<Hello>Hai</Hello>
               var urlLdr:URLLoader = new URLLoader();
               var urlRqst:URLRequest = new URLRequest ("AppData.xml");
               urlRqst.data=FileData;
                urlRqst.contentType = "text/xml";
               urlRqst.method = URLRequestMethod.POST;
               urlLdr.load(urlRqst);
This AppData file already exist and has some data in it.

   How to find the application is exiting.

Answer 1

use:  fscommand('Quit');
to exit your app.
and this is how you would use the urlloader class to save data:
public function UpdateData():void
         trace("Closing....");
          var FileData:XML=<Hello>Hai</Hello>
var urlVar:URLVariables=new URLVariables();
urlVar.fileData=FileData;
            var urlLdr:URLLoader = new URLLoader();
           var urlRqst:URLRequest = new URLRequest ("this must be an executable to parse and write data");
           urlRqst.data=urlVar;
           urlRqst.contentType = "text/xml";
               urlRqst.method = URLRequestMethod.POST;
              urlLdr.load(urlRqst);
but i don't think you can use an executable on a fl4 device so you will need to use a different class.  i don' know how you're storing an xml file on a fl4 device but you should be able to use the sharedobject to read and store xml.
