XmlDocumentFragment.CloneNode(Boolean) Method

Definition

Creates a duplicate of this node.

public:
 override System::Xml::XmlNode ^ CloneNode(bool deep);
public override System.Xml.XmlNode CloneNode (bool deep);
override this.CloneNode : bool -> System.Xml.XmlNode
Public Overrides Function CloneNode (deep As Boolean) As XmlNode

Parameters

deep
Boolean

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

Returns

The cloned node.

Examples

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( "<items/>" );
   
   // Create a document fragment.
   XmlDocumentFragment^ docFrag = doc->CreateDocumentFragment();
   
   // Set the contents of the document fragment.
   docFrag->InnerXml = "<item>widget</item>";
   
   // Create a deep clone.  The cloned node
   // includes child nodes.
   XmlNode^ deep = docFrag->CloneNode( true );
   Console::WriteLine( "Name: {0}", deep->Name );
   Console::WriteLine( "OuterXml: {0}", deep->OuterXml );
   
   // Create a shallow clone.  The cloned node does
   // not include any child nodes.
   XmlNode^ shallow = docFrag->CloneNode( false );
   Console::WriteLine( "Name: {0}", shallow->Name );
   Console::WriteLine( "OuterXml: {0}", shallow->OuterXml );
}
using System;
using System.IO;
using System.Xml;

public class Sample
{
  public static void Main()
  {

    // Create the XmlDocument.
    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<items/>");

    // Create a document fragment.
    XmlDocumentFragment docFrag = doc.CreateDocumentFragment();

    // Set the contents of the document fragment.
    docFrag.InnerXml ="<item>widget</item>";

    // Create a deep clone.  The cloned node
    // includes child nodes.
    XmlNode deep = docFrag.CloneNode(true);
    Console.WriteLine("Name: " + deep.Name);
    Console.WriteLine("OuterXml: " + deep.OuterXml);

    // Create a shallow clone.  The cloned node does
    // not include any child nodes.
    XmlNode shallow = docFrag.CloneNode(false);
    Console.WriteLine("Name: " + shallow.Name);
    Console.WriteLine("OuterXml: " + shallow.OuterXml);
  }
}
Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()
    
    ' Create the XmlDocument.
    Dim doc as XmlDocument  = new XmlDocument()
    doc.LoadXml("<items/>")

    ' Create a document fragment.
    Dim docFrag as XmlDocumentFragment = doc.CreateDocumentFragment()

    ' Set the contents of the document fragment.
    docFrag.InnerXml ="<item>widget</item>"

    ' Create a deep clone.  The cloned node
    ' includes child nodes.
    Dim deep as XmlNode = docFrag.CloneNode(true)
    Console.WriteLine("Name: " + deep.Name)
    Console.WriteLine("OuterXml: " + deep.OuterXml)

    ' Create a shallow clone.  The cloned node does
    ' not include any child nodes.
    Dim shallow as XmlNode = docFrag.CloneNode(false)
    Console.WriteLine("Name: " + shallow.Name)
    Console.WriteLine("OuterXml: " + shallow.OuterXml)    

  end sub
end class

Remarks

CloneNode serves as a copy constructor for nodes. To see how this method behaves with other node types, see XmlNode.CloneNode.

The cloned node has no parent (ParentNode returns null).
