XmlElement.CloneNode(Boolean) Methode

Definition

Erstellt ein Duplikat dieses Knotens.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

Parameter

deep
Boolean

true, wenn die Teilstruktur unter dem angegebenen Knoten rekursiv geklont werden soll, false, wenn nur der Knoten selbst (und bei einem XmlElement-Knoten auch dessen Attribute) geklont werden soll(en).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).

Gibt zurück

Der geklonte Knoten.The cloned node.

Beispiele

Im folgenden Beispiel wird ein neues-Element erstellt, geklont und dann beide-Elemente zu einem XML-Dokument hinzugefügt.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 );
}

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

public class Sample
{
  public static void Main()
  {

    XmlDocument doc = new 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);
  }
}

Hinweise

Diese Methode dient als Kopierkonstruktor für-Knoten.This method serves as a copy constructor for nodes. Der doppelte Knoten besitzt kein übergeordnetes Element (ParentNode null) zurück.The duplicate node has no parent (ParentNode returns null).
