Definice

Obor názvů:

System.Xml

Sestavení:

System.Xml.ReaderWriter.dll

Zdroj:

XmlDocumentFragment.cs

Vytvoří duplikát tohoto uzlu.

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

Parametry

deep

Boolean

true rekurzivně klonovat podstrom pod zadaným uzlem; false pro klonování pouze samotného uzlu.

Návraty

XmlNode

Klonovaný uzel.

Příklady

Následující příklad ukazuje rozdíl mezi hlubokým a mělkým klonem.

#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);
  }
}

    ' 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)

Poznámky

CloneNode slouží jako konstruktor kopírování pro uzly. Pokud chcete zjistit, jak se tato metoda chová s jinými typy uzlů, projděte si téma XmlNode.CloneNode.

Klonovaný uzel nemá žádný nadřazený uzel (ParentNode vrátí null).
