XmlNode.RemoveAll Method

Definition

Namespace:

System.Xml

Assemblies:

netstandard.dll, System.Xml.ReaderWriter.dll

Source:

XmlNode.cs

Removes all the child nodes and/or attributes of the current node.

C#

public virtual void RemoveAll();

Examples

The following example removes all child and attribute nodes from the root node.

C#

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

public class Sample {

  public static void Main() {

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

    XmlNode root = doc.DocumentElement;

    //Remove all attribute and child nodes.
    root.RemoveAll();

    Console.WriteLine("Display the modified XML...");
    doc.Save(Console.Out);
  }
}

Remarks

If a removed attribute is known to have a default value, an attribute immediately appears containing the default value and, if applicable, the corresponding namespace URI, local name, and prefix.

This method is a Microsoft extension to the Document Object Model (DOM).

Notes to Inheritors

When overriding RemoveAll in a derived class, in order for events to be raised correctly, you must call the RemoveAll method of the base class.
