Error while parsing HTML with PHP

Question

I'm trying to parse some HTML. This is my code:

xml_parse_into_struct($p, $initpage, $values);
foreach ($values as $key => $val) {
    if (($val['tag'] == 'INPUT') && ($val['attributes']['name'] == 'authenticity_token')) {
        $token = $val['attributes']['value'];
        break;
    }
}
echo $token;

No problems with the curl or the XML parsing... I know that $values includes the goodies, as print_r($values) wil output, amongst other things, this:

[48] => Array
   (
       [tag] => INPUT
       [type] => complete
       [level] => 8
       [attributes] => Array
            (
                [NAME] => authenticity_token
                [TYPE] => hidden
                [VALUE] => d76a4bec329537ac3322
            )

    )

When I try running the code, however, I get this error:

PHP Notice: Undefined variable: token in /media/.sda3/pjotr/scripts/tweet.php on line 49

Keys are case sensitive. You check for name, which doesn't match NAME. Same goes for value, of course, so you need to fix that too.
