HTTP POST Xml string

[Navitas]

Help!

I need to post an xml string to a server. I've almost got it working but a couple of things are proving difficult. Here is the code (where 'output' is a string of xml):

Dim Gateways(1) As String
            Gateways(0) = "[URL unfurl="true"]http://xml3.mblox.com:8180/send"[/URL]
            Gateways(1) = "[URL unfurl="true"]http://xml4.mblox.com:8180/send"[/URL]
            'output = HttpUtility.UrlEncode(output)
            Dim web As New WebClient
            web.Headers.Add("Content-Type", "application/x-[URL unfurl="true"]www-form-urlencoded")[/URL]
            Dim postData As Byte() = System.Text.Encoding.ASCII.GetBytes(output)
            For Each gWay As String In Gateways
                Dim response As Byte() = web.UploadData(gWay, postData)
                Console.Write(System.Text.Encoding.ASCII.GetString(response))
                Dim respXml As New XmlDocument
                respXml.LoadXml(System.Text.Encoding.ASCII.GetString(response))
                If respXml.SelectSingleNode("//RequestResultCode").InnerText = "0" Then ' success, exit loop
                    MessageBox.Show("Message sent successfully", "pnrSMS Send Results", MessageBoxButtons.OK, MessageBoxIcon.Information)
                    web.Dispose()
                    Exit For
                End If
            Next

The requirements for the post are that the data must be sent in a POST parameter called "XMLDATA=" the xmldata must be URL encoded, but the XMLDATA= part must not.

Currently I have commented out the code that I thought would URL encode the string of XML - But if I use that line the web server returns an error stating : <RequestResultText>XML-error Stopping after fatal error: The markup in the document preceding the root element must be well-formed.</RequestResultText>

Basically the above code does work except even though there is no XMLDATA= parameter (god knows how!). However the formatting is wrong as the carriage returns are not displayed.

How do I add the POST Parameter and also url Encode the output/XML string ?

Hope this made sense!

Try changing your content type to "text/xml" or "text/xml; utf-8"
