XElement.IsEmpty Property

 

Gets a value indicating whether this element contains no content.

Namespace:   System.Xml.Linq
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)

public bool IsEmpty { get; }

Property Value

Type: System.Boolean

true if this element contains no content; otherwise false.

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.

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


                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
