php dom操作存储xml节点

userdata.xml

<?xml version="1.0" encoding="ISO-8859-1"?><data><user><name>admin</name><password>123</password></user><user><name>aaa</name><password>123</password></user><user><name>bbb</name><password>123</password></user></data>

php：

<?php$xml = simplexml_load_file("userdata.xml");$array_name = array();$array_pw = array();$i = 0;$j = 0;foreach($xml->user as $user){foreach($user->name as $name){$array_name[$i] = $name;$i++;}foreach($user->password as $pw){$array_pw[$j] = $pw;$j++;}}?>

至此，userdata.xml的name标签和password标签分别存储在数组变量$array_name以及$array_pw里面。
