Почему это регулярное выражение?

Я хочу, чтобы разобрать это с помощью регулярных выражений, чтобы получить только ключи и значения без окружающих кавычек в словарь:

def load_replacement_dict(file_name): 
    with open(file_name, 'r') as f: 
     content = f.read() 
     resultDict = {} 

     dictionary_regex = re.compile('"([^"]*)" = "([^"]*)"',) 

     for result in dictionary_regex.finditer(content): 
      resultDict[result.group(1)] = result.group(2) 

     for key, value in resultDict.items(): 
      print (key+" = "+value).decode('utf-8') 

     return resultDict

Первая подгруппа но когда я добавляю что-либо после этого, он перестает соответствовать. Я пробовал использовать пространство, используя \ s, и ничто не похоже на пробелы вокруг знаков равенства. Что мне здесь не хватает?

EDIT: Я обнаружил, что если я удалю маркер порядка байтов юникода с начала файла, тогда будет работать регулярное выражение. Не решение очевидно, но, возможно, подсказка о том, как можно модифицировать регулярное выражение?

[Regexplanet] (http://www.regexplanet.com/advanced/python/index.html) может вам помочь. Как бы то ни было, я не знаю, чего вы хотите или чего не хотите, но в регулярном выражении в коде отсутствует буквальная двойная кавычка вокруг второй группы захвата. –

Отредактировано для исправления кавычек. У меня были они, но я удалял вещи, пытаясь заставить их работать и забыл прочитать вопрос. –

Возможно ли, чтобы инженер предоставил комментарий? –

В конечном итоге это проблема с кодировкой. Файл был UTF-16. Размещен:

with codecs.open(file_name, 'r', 'utf-16') as f:

Регулярно работает нормально.

Чтобы избежать сбежавших проблем цитаты, вы можете использовать этот

"((?:[^"]+|(?<=\\)")*)" = "((?:[^"]+|(?<=\\)")*)"

Мне кажется, что то, что вы пытаетесь достичь может быть проще сделать при помощи строковых методов вместо регулярных выражений:

>>> s = '"A Key With \"quotes\" in it" = " Another Value "' 
>>> l,r = [v.strip().strip('"').strip() for v in s.split('=')] 
>>> l,r 
('A Key With "quotes" in it', 'Another Value')

Ускорение будет сохранено, оно потеряется выше только из-за того, как я создал строку. Я прочитать текст из файла, то, что происходит это:

In [1]: lines = open('x.txt').read().splitlines() 

In [2]: for s in lines: print [v.strip().strip('"').strip() for v in s.split('=')] 
    ...: 
['Some Key', 'Some Value'] 
['Another Key', 'Another Value'] 
['A Key With \\"quotes\\" in it', 'Another Value']

Это лучший подход. –

'' 'должен быть' '' ключ с \\ "кавычками \\" в нем "=" другое значение "''. – falsetru

Ключи и значения должны оставаться экранированными –

Вы не проверяя кавычки значения в регулярном выражении, поэтому он не может сравниться. Кроме того, чтобы обрабатывать сбежавшую кавычку внутри ключа или значения, я верю, это должно покрыть:

dictionary_regex = re.compile(r'"((?:(?:\\")|[^"])*)" = "((?:(?:\\")|[^"])*)"')

С образцами ключевых парами значений, которые были опубликованы следующим регулярное выражение, кажется, работает:

re.compile('"(.*)" = "(.*)"')

Я что-то упускаю?
