XSD - Complex Types

复杂的要素是可包含其他内容和(或)属性的XML要素。 我们可以以两种方式形成一个复杂的要素:

界定一种复杂的类型,然后使用 类型设定一个要素。 属性

直接通过点名确定复杂类型

Define a Complex Type and then create an element using type attribute.

<xs:complexType name = "StudentType">
   <xs:sequence>
      <xs:element name = "firstname" type = "xs:string"/>
      <xs:element name = "lastname" type = "xs:string"/>
      <xs:element name = "nickname" type = "xs:string"/>
      <xs:element name = "marks" type = "xs:positiveInteger"/>
   </xs:sequence>
   <xs:attribute name =  rollno  type =  xs:positiveInteger />
</xs:complexType>

<xs:element name =  student  type =  StudentType  />			 

Define a Complex Type directly by naming.

<xs:element name = "student">
   <xs:complexType>   
      <xs:sequence>
         <xs:element name = "firstname" type = "xs:string"/>
         <xs:element name = "lastname" type = "xs:string"/>
         <xs:element name = "nickname" type = "xs:string"/>
         <xs:element name = "marks" type = "xs:positiveInteger"/>
      </xs:sequence>
   <xs:attribute name =  rollno  type =  xs:positiveInteger />
   </xs:complexType>
<xs:element>
