学习J2EE第5天(Simple API for XML)[1]

今天我学习了SAX的一些基础知识.
在网上看到了sun技术社区的一篇文章《使用JAXP处理XML文件》
这篇文章网址是

我觉得他的算法太麻烦，自己想了一个简单点的,例子里的xml文件是向作者借来的,thx.

一、xml文件以及源代码
Test.xml
<?xml version="1.0" ?>
<customers>
  <customer>
    <id>#001</id>
    <name>Micke</name>
    <address>Najing</address>
  </customer>
  <customer>
    <id>#002</id>
    <name>Car</name>
    <address>Suzhou</address>
  </customer>
  <customer>
    <id>#003</id>
    <name>Jimmy</name>
    <address>ChengDu</address>
  </customer>
  <customer>
    <id>#004</id>
    <name>Henry</name>
    <address>Xi'an</address>
  </customer>
</customers>
