Hi there!

Do you really want a xml approach ?

I'm used to send vars to ASP.Net in the usual way:

IN THE FLASH

Make a button and give the instance name: my_send_button
make 3 imput fields with the instance name: first_name, last_name and email

Put this code in the frame:

// creates a new instance of LoadVars
var send_rec:LoadVars = new LoadVars()
// Creates a onRelease function for your button
my_send_button.onRelease = function()
{
      // Populate your LoadVars with the arguments you want to send to the ASP
      send_rec.first_name = first_name.text;
      send_rec.last_name = last_name.text;
      send_rec.email = email.text;
      // Now send the LoadVars to the ASP and Places the response in this same LoadVars
      send_rec.sendAndLoad("http://your_site_here/your_ASP_file",send_rec,"GET");
}
/* After send and recieve ALL variables (or at last tried to), the onLoad function
will be called (This will be automactly called when all done)*/
send_rec.onLoad = function(sucess:Boolean)
{
      // If all good
      if (sucess)
      {
             // This message will be generated by your ASP
            trace(send_rec.final_message);
      }
}

IN THE ASP.NET

<%@ Page Language="VB" debug="true"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<script runat="server">
    Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
        Response.Expires = -1
        Response.AddHeader("Pragma", "no-cache")
        Response.CacheControl = "no-cache"
        Response.AddHeader("Content-Type", "text/html;")
        Dim first_name as String
        Dim last_name as String
        Dim email as String
        first_name = Request("first_name")
        last_name = Request("last_name")
        email = Request("email")
        if (first_name <> "") and (last_name <> "") and (email <> "") Then
            Response.Write("&final_message=Everything is fine&")
        else
            Response.Write("&final_message=One of the fields is blank&")
        End if
    End Sub
</script>

Well thats it. I hope it helps :)
