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)

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

public abstract function get IsEmptyElement () : boolean

Property Value

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

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.

The following example displays the text content of each element.

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.
