true to recursively clone the subtree under the specified node; false to clone only the node itself. Because comment nodes do not have children, the cloned node always includes the text content, regardless of the parameter setting.
Returns
The cloned node.
Remarks
CloneNode serves as a copy constructor for nodes. To see how this method behaves with other node types, see the XmlNode.CloneNode(bool) method in the XmlNode class.
