XSD Complex Types With Mixed Content
A mixed complex type element can contain attributes,
elements, and text.
Complex Types with Mixed Content
An XML element, "letter", that contains both text and other elements:
<letter>
Dear Mr.<name>John Smith</name>.
Your order <orderid>1032</orderid>
will be shipped on <shipdate>2001-07-13</shipdate>.
</letter>
|
The following schema
declares the "letter" element:
<xs:element name="letter">
<xs:complexType mixed="true">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="orderid" type="xs:positiveInteger"/>
<xs:element name="shipdate" type="xs:date"/>
</xs:sequence>
</xs:complexType>
</xs:element>
|
Note: To enable character data to appear between the child-elements of
"letter", the mixed attribute must be set to "true". The <xs:sequence> tag means
that the elements defined (name, orderid and shipdate) must appear in that order
inside a "letter" element.
We could also give the complexType element a name, and let the "letter" 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="letter" type="lettertype"/>
<xs:complexType name="lettertype" mixed="true">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="orderid" type="xs:positiveInteger"/>
<xs:element name="shipdate" type="xs:date"/>
</xs:sequence>
</xs:complexType>
