XmlDocumentFragment.CloneNode(Boolean) Méthode

Définition

Espace de noms:

System.Xml

Assembly:

System.Xml.ReaderWriter.dll

Source:

XmlDocumentFragment.cs

Crée un doublon de ce nœud.

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

Paramètres

deep

Boolean

true pour cloner récursivement la sous-arborescence sous le nœud spécifié ; false pour cloner seulement le nœud lui-même.

Retours

XmlNode

Nœud cloné.

Exemples

L’exemple suivant montre la différence entre un clone profond et superficiel.

#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;

    // Set the contents of the document fragment.

    // 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

public class Sample

  public shared sub Main()

    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

Remarques

CloneNode sert de constructeur de copie pour les nœuds. Pour voir comment cette méthode se comporte avec d’autres types de nœuds, consultez XmlNode.CloneNode.

Le nœud cloné n’a pas de parent (ParentNode retourne null).
