Examples

The following example creates a variety of XML trees, and shows the value of this property with each tree.

C#

XElement el1 = new XElement("Root");
Console.WriteLine(el1);
Console.WriteLine(el1.IsEmpty);
Console.WriteLine();
XElement el2 = new XElement("Root", "content");
Console.WriteLine(el2);
Console.WriteLine(el2.IsEmpty);
Console.WriteLine();
XElement el3 = new XElement("Root", "");
Console.WriteLine(el3);
Console.WriteLine(el3.IsEmpty);
Console.WriteLine();
el3.ReplaceAll(null);
Console.WriteLine(el3);
Console.WriteLine(el3.IsEmpty);

This example produces the following output:

<Root />
True

<Root>content</Root>
False

<Root></Root>
False

<Root />
True

Remarks

Note that an element that contains a start and end tag with no content between the tags is not considered to be an empty element. It has content with no length. Only an element that contains only a start tag, and is expressed as a terminated empty element, is considered to be empty.
