XSD 对 XML 数据格式验证 java

========xsd文件，文件名bean.xsd，放在当前java文件目录下

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="bean">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="name" type="xs:string"/>
                <xs:element name="address" type="xs:string"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

========被验证xml文件，文件名bean.xml，放在当前java文件目录下

<?xml version="1.0" encoding="UTF-8"?>
<bean>
    <name>rain </name>
    <address>中国</address>
</bean>
