XML多子元素、多属性及XSD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="beans">
		<xs:complexType>
			<xs:sequence>
				<xs:element name="bean" minOccurs="0"
					maxOccurs="unbounded">
					<xs:complexType>
						<xs:sequence>
							<xs:element name="name" type="xs:string" />
							<xs:element name="address" type="xs:string" />
						</xs:sequence>
						<xs:attribute name="smallrainIdIn" type="xs:string" use="required"/>
            <xs:attribute name="smallrainAttributeIn" type="xs:string" use="optional"/>
					</xs:complexType>
				</xs:element>
			</xs:sequence>
			<xs:attribute name="smallrainId" type="xs:string" use="required"/>
            <xs:attribute name="smallrainAttribute" type="xs:string" use="optional"/>
		</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"?>
<beans smallrainId="01">
	<bean smallrainIdIn="11">
		<name>rain </name>
		<address>中国</address>
	</bean>
	<bean smallrainIdIn="12">
		<name>rain one</name>
		<address>中国 one</address>
	</bean>
</beans>
