REGEX-String和轉義報價

Question

如何獲得以下兩個文本中引號之間的內容？

text_1 = r""" "Some text on \"two\" lines with a backslash escaped\\" \
     + "Another text on \"three\" lines" """

text_2 = r""" "Some text on \"two\" lines with a backslash escaped\\" + "Another text on \"three\" lines" """

對我來說問題是，如果它們被轉義，應該忽略引號，但是有可能使反斜杠轉義。

我想獲得以下小組。

[
    r'Some text on \"two\" lines with a backslash escaped\\',
    r'Another text on \"three\" lines'
]

Answer 1

"(?:\\.|[^"\\])*"

匹配帶引號的字符串，包括其中出現的任何轉義字符。

說明：

"       # Match a quote.
(?:     # Either match...
 \\.    # an escaped character
|       # or
 [^"\\] # any character except quote or backslash.
)*      # Repeat any number of times.
"       # Match another quote.

Answer 2

匹配除雙引號外的所有內容：

import re
text = "Some text on \"two\" lines" + "Another text on \"three\" lines"
print re.findall(r'"([^"]*)"', text)

產量

['two', 'three']

Answer 3

>>> import re
>>> text_1 = r""" "Some text on \"two\" lines with a backslash escaped\\" \
     + "Another text on \"three\" lines" """
>>> text_2 = r""" "Some text on \"two\" lines with a backslash escaped\\" + "Another text on \"three\" lines" """
>>> re.findall(r'\\"([^"]+)\\"', text_2)
['two', 'three']
>>> re.findall(r'\\"([^"]+)\\"', text_1)
['two', 'three']

也許你想要這個：

re.findall(r'\\"((?:(?<!\\)[^"])+)\\"', text)

Answer 4

>>> import re
>>> text = "Some text on\n\"two\"lines" + "Another texton\n\"three\"\nlines"
>>> re.findall(r'"(.*)"', text)
["two", "three"]
