XML引入多scheme文件约束简单示例

XML引入多scheme文件约束简单示例，用company.xsd和department.xsd来约束company.xml：

company.xsd

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://www.example.org/company"
elementFormDefault="qualified">
    <element name="company">
        <complexType>
            <sequence>
                <element name="employee">
                    <complexType>
                        <sequence>
                            <!-- 引用任何一个元素 -->
                            <any></any>
                            <!-- 员工名称 -->
                            <element name="name"></element>
                        </sequence>
                        <!-- 为employee元素添加属性 -->
                        <attribute name="age" type="int"></attribute>
                    </complexType>
                </element>
            </sequence>
        </complexType>
    </element>
</schema>

department.xsd

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
 targetNamespace="http://www.example.org/department"
 elementFormDefault="qualified">
 <!-- 部门名称 -->
 <element name="name" type="string"></element>
</schema

company.xml

<?xml version="1.0" encoding="UTF-8"?>
<!-- 数据文件 引用多个Schema -->
<company xmlns = "http://www.example.org/company"
    xmlns:dept="http://www.example.org/department"
    xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.example.org/company company.xsd http://www.example.org/department department.xsd"
>
    <employee age="30">
        <!-- 部门名称 -->
        <dept:name>人力资源部</dept:name>
        <!-- 员工名称 -->
        <name>王晓晓</name>
    </employee>
</company>
