                            [Produkt] => product1
                        )
                    [1] => Array

i'm not sure i understand what you wanna do. if you want to write to screen

foreach ($a as $date) {
    foreach ($date as $product) {
        $date_lp = $product['LP'];
        if ($date_lp !== $last_date_lp) {
            $last_date_lp = $date_lp;
            $output .= "\t\t\t<ID>{$date_lp}</ID>\n";
        }
        $output .= "\t\t\t<Produkt>{$product['Produkt']}</Produkt>\n";
    }
}

if your intention is to convert this array to xml then read this question about converting associative array to xml.
