Assuming you need to load an xml file that already exists from you file system, here is the easiest way to accomplish what your asking.

        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.Load(@"<The absolute path of your xml document>");
        XmlNode node = xmlDoc.DocumentElement;

        XmlElement element = xmlDoc.CreateElement("difficulty");
        element.Prefix = "d2I_2p0";
        node.AppendChild(element);

        xmlDoc.Save(@"<path you would like to save the file to>");
