Помогите добавить параметр description в выглузку xml

[v.kravez]

Здравствуйте.
Помогите пожалуйста добавить писание в выгрузку xml.
В коде не очень еще силен.
Есть два файла hotline.php и hotline.xml
Пробовал добавить строку: <description>' . $product['product_desc'] . '</description>
Но результата нет.
