.NET Framework Class Library
XmlReader..::.IsEmptyElement Property

When overridden in a derived class, 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)
Syntax

Visual Basic (Declaration)
Public MustOverride ReadOnly Property IsEmptyElement As Boolean
Visual Basic (Usage)
Dim instance As XmlReader
Dim value As Boolean

value = instance.IsEmptyElement
C#
public abstract bool IsEmptyElement { get; }
Visual C++
public:
virtual property bool IsEmptyElement {
    bool get () abstract;
}
JScript
public abstract function get IsEmptyElement () : boolean

Property Value

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

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

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

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

A corresponding EndElement node is not generated for empty elements.

If default content has been added to an element due to schema validation, IsEmptyElement still returns true. It has no bearing on whether or not the element has a default value. In other words, IsEmptyElement simply reports whether or not the element in the source document had an end element tag.

Examples

The following example displays the text content of each element.

Visual Basic
While reader.Read()
  If reader.IsStartElement() Then
    If reader.IsEmptyElement Then
      Console.WriteLine("<{0}/>", reader.Name)
    Else
      Console.Write("<{0}> ", reader.Name)
      reader.Read() ' Read the start tag.
      If reader.IsStartElement() Then ' Handle nested elements.
        Console.Write(vbCr + vbLf + "<{0}>", reader.Name)
      End If
      Console.WriteLine(reader.ReadString()) 'Read the text content of the element.
    End If
  End If
End While
C#
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.
    }
  } 
} 

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