Overview

Complex-type elements have attributes, child elements, or some combination of the two. For example, the Name and HomePage elements below are both complex-type elements.

Code Sample:

ComplexTypes/Demos/ComplexType.xml
<?xml version="1.0"?>
<Person>
	<Name>
		<FirstName>Mark</FirstName>
		<LastName>Twain</LastName>
	</Name>
	<HomePage URL="http://www.marktwain.com"/>
</Person>

As the diagram below shows, a complex-type element can be empty, contain simple content such as a string, or can contain complex content such as a sequence of elements.

Whereas it is not necessary to explicitly declare that a simple-type element is a simple type, it is necessary to specify that a complex-type element is a complex type. This is done with the xs:complexType element as shown below.

<xs:element name="ElementName"> <xs:complexType> <!--Content Model Goes Here--> </xs:complexType> </xs:element>
