如下xml文件
<?................?><users>
<user name="one">
<username>one</username>
<password>123</password>
<user>
<user name="two">
<username>two</username>
<password>123</password>
<user> <user name="three">
<username>three</username>
<password>123</password>
<user>
</users>我想根据user节点的name属性，取得每个user下面的username和password，代码该如何写呢？谢谢

路径改一下即可。
