XmlElement::CloneNode Method

Creates a duplicate of this node.

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

virtual XmlNode^ CloneNode(
	bool deep
) override


Type: System::Boolean
true to recursively clone the subtree under the specified node; false to clone only the node itself (and its attributes if the node is an XmlElement).

Return Value

Type: System.Xml::XmlNode
The cloned node.

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

The following example creates a new element, clones it, and then adds both elements into an XML document.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
   XmlDocument^ doc = gcnew XmlDocument;
   doc->Load( "2books.xml" );

   // Create a new element.
   XmlElement^ elem = doc->CreateElement( "misc" );
   elem->InnerText = "hardcover";
   elem->SetAttribute( "publisher", "WorldWide Publishing" );

   // Clone the element so we can add one to each of the book nodes.
   XmlNode^ elem2 = elem->CloneNode( true );

   // Add the new elements.
   doc->DocumentElement->FirstChild->AppendChild( elem );
   doc->DocumentElement->LastChild->AppendChild( elem2 );
   Console::WriteLine( "Display the modified XML..." );
   doc->Save( Console::Out );
