Weird Respone из Amazon Marketplace API, используя их библиотеку PHP

Question

Каждый. Я здесь абсолютный любитель, поэтому, пожалуйста, потерпите меня, я был бы признателен за любую помощь. Я пытаюсь работать с Amazon MWS API, используя их клиентскую библиотеку PHP. После нескольких настроек я успешно получил ответ от сервера. Ответ должен быть просто немного XML, но текст ответа - это нечто другое. Похоже, что xml ответа был преобразован в массив тегов, но ни одно из значений не присутствует. Я удалил код, который был предоставлен с библиотекой, чтобы напечатать только xml ответа, и он все еще отображает следующий текст. Это только верхняя часть текста, но это должно сработать. Если бы кто-то мог сказать мне, почему ответ находится в этом массиве без значений элементов XML, я был бы очень признателен за это.

Спасибо за ваше время.

            print_r($response);
