Returning XML from MVC Controller Action

To return xml from a mvc controller action we can use the following code:

public XmlElement name_of_function()
{
      XmlDocument Feed = new XmlDocument();
      XmlWriter Write = Feed.CreateNavigator().AppendChild();

      Write.WriteStartDocument();
      Write.WriteStartElement("head");
      Write.WriteElementString("name_of_tag", "value");
      Write.WriteEndElement();
      Write.WriteEndDocument();

      Write.Flush();
      Write.Close()

      return Feed.DocumentElement;
}
