dom4j解析xml实例(2)

dom4j是一个java的XML API，类似jdom，用来读写XML文件，它性能优异、功能强大和极易使用等特点

所用jar包：dom4j-1.6.1.jar、jaxen-1.1-beta-6.jar

需要解析的xml文件：people.xml

1 2 3 4 5 6

<people city="shenzhen">      <student name="milton" age="22"></student>      <student name="lego" age="23"></student>      <teacher name="bruce" age="27"></teacher>      <teacher name="ziven" age="28"></teacher>  </people>

 

java代码如下：
