How to access XML data from Submit Button in .NET

[KToor]

Hey everyone, I've created a form using LiveCycle designer, and have a submit button to send XML data to my webserver.

<submit textEncoding="UTF-8" target="http://localhost:57179/default.aspx" embedPDF="1" format="xml"/>

What i need is to have an XML document that I can parse the data from and send it to my database.  I've got the parsing to database part down, but I can't figure out how to get the data from the PDF to my application.

What exactly is being sent when the button is clicked and how?  And how do I retrieve the XML??  it isn't a through a traditional GET/POST method is it??

I've attached the beginning part of my working code if that's of any help.  But it is simply using a saved xml document, not one coming from a PDF.

5.     <%@ Import Namespace="System.Data" %> 
6.     <%@ Import Namespace="System.Data.SqlClient" %> 
7.     <%@ Import Namespace="System.Text"%>

12.     Protected Overloads Sub Page_Load(ByVal source As Object, ByVal e As EventArgs) 
13.         Dim doc As New XmlDocument 
14.         doc.Load(Server.MapPath("~/App_Data/test.xml")) 
15.         Dim root As XmlNode 
16.         root = doc.DocumentElement
