true to recursively clone the subtree under the specified node; false to clone only the node itself. Because CDATA nodes do not have children, regardless of the parameter setting, the cloned node will always include the data content.
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.
