Then use it

function Xml_to_array ($xml)
{
    $reg = "/< (\\w+) [^>]*?> ([\\x00-\\xff]*?) <\\/\\1>/";
    if (Preg_match_all ($reg, $xml, $matches))
    {
        $count = count ($matches [0]);
        $arr = Array ();
        for ($i = 0; $i < $count; $i + +)
        {
            $key = $matches [1][$i];
            $val = Xml_to_array ($matches [2][$i]);  Recursive
            if (Array_key_exists ($key, $arr))
            {
                if (Is_array ($arr [$key]))
                {
                    if (!array_key_exists (0, $arr [$key]))
                    {
                        $arr [$key] = Array ($arr [$key]);
