php xml操作

<? xml version="1.0" encoding="UTF-8" ?>
< root >
< admins >
< username >admin </ username >
< password >xxxxxxxxxxxxxx </ password >
</ admins >
< admins >
< username >admin </ username >
< password >xxxxxxxxxxxxxx </ password >
</ admins >
</ root >

$filex = S_ROOT.'./data/adminconfig.xml';
$xml =  simplexml_load_file( $filex);
$result =  $xml->xpath("//admins[username='". $_SESSION['user']."']");

$result[0]->password =  md5( $_POST['newpwd']);   // 关键在于 $result[0] 这里dump打印出来看结果就很明显了. 因为是xml对象 不能像数组那样直接复制  所有 xml -> tag
