Как поживаешь? Мне нужно сделать сценарий для синтаксического анализа входного файла xml в файл json. Я старался изо всех сил, но было бы хорошо, если бы вы могли проверить это и помочь мне улучшить его. Идея в том, что я не использую objectify библиотек, которые напрямую конвертируют файлы. Я должен написать эти сценарии, по крайней мере, со следующими свойствами: —
Тип сиденья / элемента (сиденье, кухня, ванная и т. Д.) —
Элемент списка
Идентификационный номер места (17A, 18A)
Стоимость места
Класс кабины
Доступность
Кстати, мне не удалось найти тип сиденья / элемента для каждого сиденья.

from collections import OrderedDict
xmlFile = xml.dom.minidom.parse("seatmap1.xml")
def set_amount(element_to_analyze, element_to_change):
if element_to_analyze.getAttribute('AvailableInd') == 'true':
element_to_change['seat_price'] = seat.getElementsByTagName('ns:Service')[0].getElementsByTagName(
'ns:Fee')[0].getAttribute('Amount')

flight_data['DepartureAirport'] = plane_data.getElementsByTagName('ns:DepartureAirport')[0].getAttribute(

Здесь много всего происходит, и проблема очень плохо определена. Я понимаю, что вас попросили сделать это (где исходное описание проблемы?) Для заявления о приеме на работу, так что, возможно, они оставили кучу открытыми для интерпретации, но в любом случае:
Обычно в Интернете ходят слухи, что etree — это интерфейс синтаксического анализа XML, который больше похож на Pythonic по сравнению с minidom. Видеть https://stackoverflow.com/a/8022507/313768 Например. Очень неясно, будут ли ограничения производительности подталкивать вас к lxml. Я считаю, что интерфейс etree более естественен, поэтому я показал его в своем примере кода, но minidom «тоже в порядке». Не идеально, если вы часто просите все совпадающие теги обращать внимание только на первый. Я показал довольно строгую схему навигации xpath, которая не заставляет синтаксический анализатор выполнять поиск по всему дереву и запрашивает только один элемент, когда это требуется.
Ваш set_amount это несколько странный блок кода для извлечения в функцию. Он не имеет возвращаемых значений и изменяет element_to_change на месте. В целом функции подходят лучше, если они возвращают значения и не изменяют свои члены. Подход Python к этому совершенно слабый, но если вы когда-нибудь переключитесь на функциональный язык, это станет большим фактором.
Вы определяете str_to_bool но затем не использовать его в set_amount. Это настолько простая операция, что ее, вероятно, не стоит фиксировать в функции, и ее можно выполнить в строке с == 'true' сказуемое и нет if-заявления.
Ваше использование OrderedDict не обязательно для любая современная версия Python.
Ваш Document проверка выполняется наизнанку и в обратном направлении — вместо того, чтобы проверять наличие полностью несвязанного элемента, вы должны проверять наличие отсутствие элемента, на который вы полагаетесь, чтобы сгенерировать текущий тип документа. Это может быть представлено, например, как исключение, созданное конструктором в том виде, в котором он есть у меня. Более изящные шаблоны могут использовать фабрику, которая проверяет документ на синтаксическом разборе и раскручивает правильный класс загрузки, но ваш вопрос не имеет достаточного контекста, чтобы оправдать это.
Вы объединили две операции в одну: загрузку из XML в четко определенное представление в памяти и сериализацию в JSON-совместимые словари. Я показал, как их можно разделить.
Не звони outfile.write(dumps; просто позвони dump который принимает файловый формат.
