I am trying to read xml from web response and get selected nodes from it. This is what I have so far and its throwing me a blank web page.

WRequest method, sends a POST request to url using web request and returns a string xml response such as:

HTML

<status> <code>201</code>
<resources_created>
<link href="####" rel="############" title="####" /> 
</resources_created> 
<warnings> <warning>display_date is read-only</warning> </warnings> 
</status>

C#

public static string readUri2()
        {
            string uri = "";
            string xml = WRequest();

            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.LoadXml(xml);

            XmlNodeList nodes = xmlDoc.SelectNodes(@"Status");
            foreach (XmlNode node in nodes)
            {
                string tempf = node["resources_created"].InnerText;
                uri = tempf;
            };
            return uri;
        }

C#

protected void Page_Load(object sender, EventArgs e)
        {
            string uri = readUri2();
            Label1.Text = Server.HtmlEncode(uri);

        }

Any help would be very much appreciated. Many thanks.

How about using the debugger to see what's returned from your readUri2 method?

You should use a Stream Reader to obtain the data from the Webrequest. Here is an example you can adapt to your code.

private void Main_Load(object sender, EventArgs e)
{
    WebRequest request = WebRequest.Create("Your XML File Location Here");
    request.Credentials = CredentialCache.DefaultCredentials;
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    Stream iDataStream = response.GetResponseStream();
    StreamReader reader = new StreamReader(iDataStream);
    string eresponse = reader.ReadToEnd();
    MessageBox.Show(eresponse);
    reader.Close();
    iDataStream.Close();
    response.Close();
}
