DOM解析XML文件

XML文件样例：

<?xml version="1.0" encoding="UTF-8"?>
<students>
	<stu>
		<name>张三</name>
		<age>23</age>
		<sex>男</sex>
		<love>
			<love1>骑行1</love1>
			<love2>登山1</love2>
		</love>
	</stu>
	<stu>
		<name>李四</name>
		<age>22</age>
		<sex>女</sex>
	</stu>
</students>

Student实体类有3个属性：name、age、sex
