How do I create an xmlElement from the current node of a xmlReader?

XmlDocument doc = new XmlDocument();
    doc.Load(reader);
    XmlElement el = doc.DocumentElement;

doc.LoadXml(reader.ReadOuterXml());

using (XmlReader subReader = reader.ReadSubtree())
    {
        XmlDocument doc = new XmlDocument();
        doc.Load(subReader);
        XmlElement el = doc.DocumentElement;
    }

XmlElement myElement;
myXmlReader.Read();
if (myXmlReader.NodeType == XmlNodeType.Element)
{
   myElement = doc.CreateElement(myXmlReader.Name);
   myElement.InnerXml = myXmlReader.InnerXml;
}
