XmlDocument::CloneNode Method (Boolean)

 

Creates a duplicate of this node.

Namespace:   System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public:
virtual XmlNode^ CloneNode(
	bool deep
) override

Parameters

deep
Type: System::Boolean

true to recursively clone the subtree under the specified node; false to clone only the node itself.

Return Value

Type: System.Xml::XmlNode^

The cloned XmlDocument node.

This method serves as a copy constructor for nodes. The cloned node has no parent (ParentNode returns null).

If deep is true, the cloned node includes all the child nodes, otherwise only the XmlDocument node is cloned. See the XmlNode::CloneNode method to see how this method behaves on other node types.

The following example shows the difference between a deep and shallow clone.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{

   //Create the XmlDocument.
   XmlDocument^ doc = gcnew XmlDocument;
   doc->LoadXml( "<book genre='novel' ISBN='1-861001-57-5'><title>Pride And Prejudice</title></book>" );

   //Create a deep clone.  The cloned node 
   //includes the child node.
   XmlDocument^ deep = dynamic_cast<XmlDocument^>(doc->CloneNode( true ));
   Console::WriteLine( deep->ChildNodes->Count );

   //Create a shallow clone.  The cloned node does not 
   //include the child node.
   XmlDocument^ shallow = dynamic_cast<XmlDocument^>(doc->CloneNode( false ));
   Console::WriteLine( "{0}{1}", shallow->Name, shallow->OuterXml );
   Console::WriteLine( shallow->ChildNodes->Count );
}
