XSD Complex Text-Only Elements

A complex text element can contain both attributes and text.

Define Complex Text-Only Elements

This type contains only simple content (text and attributes), therefore we add a simpleContent element around the content. When using simple content, you must define an extension OR a restriction within the simpleContent element, like this:

<xs:element name="somename">
  <xs:complexType>
    <xs:simpleContent>
      <xs:extension base="basetype">
        ....
        ....
      </xs:extension>     
    </xs:simpleContent>
  </xs:complexType>
</xs:element>

<xs:element name="somename">
  <xs:complexType>
    <xs:simpleContent>
      <xs:restriction base="basetype">
        ....
        ....
      </xs:restriction>     
    </xs:simpleContent>
  </xs:complexType>
</xs:element>

Tip: Use the extension element to expand on the base simple type for the element, and use the restriction element to limit the base simple type for the element.

Here is an example of an XML element, "shoesize", that contains text-only:

<shoesize country="france">35</shoesize>

The following example declares a complexType, "shoesize". The content is defined as an integer data type and the "shoesize" element also contains an attribute named "country":

<xs:element name="shoesize">
  <xs:complexType>
    <xs:simpleContent>
      <xs:extension base="xs:integer">
        <xs:attribute name="country" type="xs:string" />
      </xs:extension>
    </xs:simpleContent>
  </xs:complexType>
</xs:element>

We could also give the complexType element a name, and let the "shoesize" element have a type attribute that refers to the name of the complexType (if you use this method, several elements can refer to the same complex type):

<xs:element name="shoesize" type="shoetype"/>

<xs:complexType name="shoetype">
  <xs:simpleContent>
    <xs:extension base="xs:integer">
      <xs:attribute name="country" type="xs:string" />
    </xs:extension>
  </xs:simpleContent>
</xs:complexType>
