Ejemplos

En el ejemplo siguiente se muestra la diferencia entre un clon profundo y uno superficial.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 );
}

using System;
using System.IO;
using System.Xml;

public class Sample

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

    //Create a shallow clone.  The cloned node does not 
    //include the child node.
    XmlDocument shallow = (XmlDocument) doc.CloneNode(false);
    Console.WriteLine(shallow.Name + shallow.OuterXml);

Comentarios

Este método sirve como constructor de copias para los nodos.This method serves as a copy constructor for nodes. El nodo clonado no tiene ningún elementoParentNode primario null(devuelve).The cloned node has no parent (ParentNode returns null).

Si deep XmlDocument es true, el nodo clonado incluye todos los nodos secundarios; de lo contrario, solo se clona el nodo.If deep is true, the cloned node includes all the child nodes, otherwise only the XmlDocument node is cloned. Vea el XmlNode.CloneNode método para ver cómo se comporta este método en otros tipos de nodo.See the XmlNode.CloneNode method to see how this method behaves on other node types.
