XmlNodeReader.IsEmptyElement Property

Gets a value indicating whether the current node is an empty element (for example, <MyElement/>).

Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)

public override bool IsEmptyElement { get; }
/** @property */
public boolean get_IsEmptyElement ()

public override function get IsEmptyElement () : boolean

Property Value

true if the current node is an element (NodeType equals XmlNodeType.Element) and it ends with />; otherwise, false.

NoteNote

In the Microsoft .NET Framework version 2.0, the recommended practice is to create XmlReader instances using the XmlReaderSettings class and the Create method. This allows you to take full advantage of all the new features introduced in the .NET Framework. For more information, see Creating XML Readers.

This property enables you to determine the difference between the following:

<item num="123"/> (IsEmptyElement is true).

<item num="123"> (IsEmptyElement is false, although element content is empty).

A corresponding EndElement node is not generated for empty elements.

The following example displays the text content of each element.

using System.IO;
using System.Xml;

{
  public static void Main()
  {
    XmlNodeReader reader = null;

    try

       //Create and load the XML document.
       XmlDocument doc = new XmlDocument();
       doc.LoadXml("<book>" +
                   "<title>Pride And Prejudice</title>" +
                   "<price>19.95</price>" +
                   "<misc/>" +
                   "</book>");
