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>
