A complex text-only element can contain text and attributes.
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> OR <xs:element name="somename"> <xs:complexType> <xs:simpleContent> <xs:restriction base="basetype"> .... .... </xs:restriction> </xs:simpleContent> </xs:complexType> </xs:element> |
Tip: Use the extension/restriction element to expand or 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 value, 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> |
