Posting xml to server and getting xml response back.

[kt366]

Please could someone explain to me how to post xml to a server and then collect the xml response. At the moment when I post to the server, the response I get is in html format and is simply the page I am posting too? I am new at this, can someone explain to me what I am doing wrong? Thanks

Are you talking about AJAX ? XMLHttpRequest, XMLHttpResponse are used to transfer data in XML format(commenly used).

You can easily find tutorials on Ajax, so, google it !!

I'm using ASP.Net 2.0 c#.

You need to use the HttpWebRequest/Response. Something like:

public void PostXml(string url, string xml, Encoding enc)
{
  byte[] bytes = enc.GetBytes(xml);
  HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url);
  request.Method = "POST";
  request.ContentLength = bytes.Length;
  request.ContentType = "text/xml";
  using (Stream requestStream = request.GetRequestStream())
  {
    requestStream.Write(bytes, 0, bytes.Length);
  }
  using (HttpWebResponse response = (HttpWebResponse) request.GetResponse())
  {
    if (response.StatusCode != HttpStatusCode.OK)
    {
      string message = String.Format("POST failed. Received HTTP {0}", response.StatusCode);
      throw new ApplicationException(message);
    }
  }
}

Thank you, I have used this, but I am still recieving an HTML response. Do you have any suggestions? thanks

What are you expecting back? Are you sure you're submitting not a web service, not just a regularly web page serving server?

I am expecting XML back, I am not submitting to a webservice, the page I am submitting to I have been given by the people who have written the system.

2 things could be wrong then.

1. Your XML is not in the correct format.
2. Something is wrong with the web server.

You'll need to contact them to find out which. If there is some documentation post a link and your XML.

What do your HTTP headers look like?

MicrosoftOfficeWebServer: 5.0_Pub Content-Length: 27141 Cache-Control: private Content-Type: text/html; charset=utf-8 Date: Mon, 24 Apr 2006 14:28:32 GMT Server: Microsoft-IIS/6.0 X-AspNet-Version: 1.1.4322 X-Powered-By: ASP.NET

Content-Type: text/html; charset=utf-8

This is probably not what you need. See Jon's post above.

The Header I gave you was from the response of the server. The Header I am sending is:
Content-Type: text/xml\r\n\r\n which looks wrong.

Are you sure you can submit XML to this webserver?
