I've been trawlling the web for hours trying to see how to receive XML doc that was sent by HTTP POST operation to my web page. But all the examples I'm finding are assuming that I'm sending a request and then processing a response.

In my case I am not sending any request, the data is sent to my web page from a 3rd party vendor using the HTML POST method, and they are not expecting any response.

I need to know how to receive the XML document and parse the data

Any clues?

This article http://www.codeproject.com/Articles/217041/Post-XML-data-From-VB-application-to-ASP-NET-Appli shows how to receive it in C#.  You actually need both sides in order to test your receive application.  I expected to find something like this for VB.NET but after a search, it was not there.  My old ASP.NET book only refers to receiving a POST in the context of a 'postback' from an ASP.NET page.

Thanks ,

I've managed to convert this to VB but I'm getting in teh build as it doesn't recognize 'Utility' in the line below

Dim strResonse As String = Utility.ReadResponseFromFile(respfilepath)

Don't know what that's about.  I have frequently seen code samples like that where one little piece is left out.

respfilepath is the xml file path so u can basically use XElement to load the xml and parse the response via xpath.
if u post the xml i can show how it is done.

this is the xml I'm receiving:

<?xml version="1.0"?>
-<root><emailAddress>fred@bill.com</emailAddress>
<fullName>Fred Bloggs</fullName>
<firstName>Fred</firstName>
<lastName>Bloggs</lastName>
<score>123</score>
</root>

there's actually a lot more elements but I cut it down for simplicity :)

which data u need to parse from the xml?
u can also create a class which reflect the xml and use deserialization to create the class instance.

The other piece of this is how do I return a specific value to the page that sent the http post request in the first place.

Currently my test page just returns: System.Byte[]
