    How to login based on XML

    comlong Level 1
      I am new for a Flex demo. The request is login and register. I want save all information in a XML file and then check it. From Adobe's demo, there are only the interface, I want to know how to implement the function and the code. If I juse this way without Java, is it possilbe to publish on a web-server?
      Thanks a lot

          check this code:

          <?xml version="1.0" encoding="utf-8"?>

          //import easing classes
          import mx.effects.easing.Bounce;

          <!--start transitions-->
          <!--applies a composite transition to the login and register states-->
          <mx:Transition fromState="*" toState="*">
