Ejemplos

En el ejemplo siguiente se muestra la diferencia entre un clon profundo y superficial.

#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);
  }
}

Comentarios

CloneNode actúa como constructor de copia para los nodos. Para ver cómo se comporta este método con otros tipos de nodo, consulte XmlNode.CloneNode.

El nodo clonado no tiene ningún elemento primario (ParentNode devuelve null).
