Esempio

L'esempio seguente mostra la differenza tra un clone profondo e superficiale.

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

public class Sample {

  public static void Main() {

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "<price>19.95</price>" +
                "</book>");

    XmlNode root = doc.FirstChild;

    //Create a deep clone.  The cloned node
    //includes the child nodes.
    XmlNode deep = root.CloneNode(true);
    Console.WriteLine(deep.OuterXml);

    //Create a shallow clone.  The cloned node does not
    //include the child nodes, but does include its attribute.
    XmlNode shallow = root.CloneNode(false);
    Console.WriteLine(shallow.OuterXml);
  }
}

Commenti

Questo metodo funge da costruttore di copia per i nodi. Il nodo duplicato non ha un elemento padre (ParentNode restituisce null).

Nella tabella seguente viene descritto il comportamento specifico per ogni XmlNodeTypeoggetto .
