Question

我需要帮助解析python中的用户输入，使用正则表达式的混合并迭代正则表达式的结果。示例输入如下所示：

KeylessBuy=f and not (Feedback.color = green or comment.color=green) 
and not "BIN State".color = white and comment="got it right"

拆分结果应为：

KeylessBuy=f
Feedback.color = green
comment.color=green
"BIN State".color = white
comment="got it right"

因此只选择那些直接围绕＆＃34; =＆＃34; -sign的部分。我试过（等等）：

    r'(\w+\s{0,}(?<!=)={1,2}(?!=)\s{0,}\w+)'
    r'|("(.*?)"\s{0,}(?<!=)={1,2}(?!=)\s{0,}\w+)'
    r'|("(.*?)"\s{0,}(?<!=)={1,2}(?!=)\s{0,}"(.*?)")'
    r'|(\w+\s{0,}(?<!=)={1,2}(?!=)\s{0,}"(.*?)")'
    r'|(\w+\s{0,}\.\w+\s{0,}(?<!=)={1,2}(?!=)\s{0,}"(.*?)")',

这只是＆＃34;几乎＆＃34;给出了正确的答案。任何帮助都非常感谢！非常感谢。标记

Answer 1

您可以使用以下内容：

>>> import re
>>> s = '''KeylessBuy=f and not (Feedback.color = green or comment.color=green) 
and not "BIN State".color = white and comment="got it right"'''
>>> m = re.findall(r'(?:[\w.]+|"[^=]*)\s*=\s*(?:\w+|"[^"]*")', s)
>>> for x in m:
...     print x

KeylessBuy=f
Feedback.color = green
comment.color=green
"BIN State".color = white
comment="got it right"

Answer 2

我得到它以匹配您正在寻找的

((?:"[^"]+")?[\w\.]+?) ?= ?((?:"[^"]+")|\w+)

您可以查看正则表达式演示here

Answer 3

这应该有效。从索引1获取匹配的组。

((\"[^=]*|[\w\.]+)\s*=\s*(\w+|\"[^"]*\"))

DEMO

示例代码：

import re
p = re.compile(ur'((\"[^=]*|[\w\.]+)\s*=\s*(\w+|\"[^"]*\"))')
test_str = u"KeylessBuy=f and not (Feedback.color = green or comment.color=green) \nand not \"BIN State\".color = white and comment=\"got it right\""

re.findall(p, test_str)

Answer 4

你可以试试下面的正则表达式，

>>> str = '''
... KeylessBuy=f and not (Feedback.color = green or comment.color=green) 
... and not "BIN State".color = white and comment="got it right"'''
>>> m = re.findall(r'(?:\"[\w ]+\")?[\w.]+\s*=\s*(?:\w+)?(?:\"[\w ]+\")?', str)
>>> m
['KeylessBuy=f', 'Feedback.color = green', 'comment.color=green', '"BIN State".color = white', 'comment="got it right"']
>>> for item in m:
...     print item
... 
KeylessBuy=f
Feedback.color = green
comment.color=green
"BIN State".color = white
comment="got it right"
