XmlTextReader.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 Value

Type: System.Boolean
true if the current node is an element (NodeType equals XmlNodeType.Element) that ends with />; otherwise, false.

NoteNote

In the .NET Framework version 2.0 release, the recommended practice is to create XmlReader instances using the XmlReader.Create method. This allows you to take full advantage of the new features introduced in this release. 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.

IsEmptyElement simply reports whether or not the element in the source document had an end element tag.

The following example displays the text content of each element.


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

public class Sample 
{
  public static void Main()
  {
    XmlTextReader reader = null;

    try
    {
       //Load the reader with the XML file.
       reader = new XmlTextReader("elems.xml");

       //Parse the XML and display the text content of each of the elements.
       while (reader.Read()){
         if (reader.IsStartElement()){
           if (reader.IsEmptyElement)
              Console.WriteLine("<{0}/>", reader.Name);
           else{
               Console.Write("<{0}> ", reader.Name);
               reader.Read(); //Read the start tag.
               if (reader.IsStartElement())  //Handle nested elements.
                 Console.Write("\r\n<{0}>", reader.Name);
               Console.WriteLine(reader.ReadString());  //Read the text content of the element.
           }
         }
       } 

     } 

     finally 
     {
        if (reader != null)
          reader.Close();
      }
  }

} // End class


The example uses the file, elems.xml, as input.
