title: XDocument or XmlDocument
body: <p>I am now learning <a href="http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx" rel="noreferrer"><code>XmlDocument</code></a> but I've just ran into <a href="http://msdn.microsoft.com/en-us/library/system.xml.linq.xdocument.aspx" rel="noreferrer"><code>XDocument</code></a> and when I try to search the difference or benefits of them I can't find something useful, could you please tell me why you would use one over another ?</p>
