How to read xml from web response? [duplicate]

This question already has an answer here:

• C# Get XML element value using XmlDocument 1 answer

I am trying to read xml from web response and get selected nodes (i.e link) from it. This is what I have so far and its showing "System.Xml.XmlElement", as an output.

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

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

ReadUri2 method

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

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

        XmlNode elem = xmlDoc.DocumentElement.FirstChild;
        uri = elem.ToString();
        return uri;

        }

PageLoad calls

 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.
