$xml_string = "<?xml version='1.0'?>
    <users>
       <user id='2' status='Admin'>
          <username>Mikki Mau</username>
          <useremail>mikki@mydomain.com</useremail>
       </user>
       <user id='3' status='User'>
          <username>Miki Mau</username>
          <useremail>mikki@mydomain.com</useremail>
       </user>
    </users>";
$xml = simplexml_load_string($xml_string);
foreach ($xml->user as $user) {
    //Get "id" and "status" attributes
    echo $user['id'].' ('.$user['status'].')<br>';
    //Get subnodes
    echo $user->username. '<br>';
    echo $user->useremail. '<br>';
