为什么我的 Python RegExp 不适用于带有进位返回的文件？

Question

I need read a file. This file contains a list with key-value. The key is always the same ['key_text'] and the value is always a text or a html or a list... My regular expression works without "carry return". But when exists \r\n or \n in "value", not works.

This is my regexp ( very bad I known ):

^[ ]*[ \t]*(\[\'([\w+\.]*)\'\])[ ]*[ \t]*\=[ ]*[ \t]*[\'\"](.*)[\'\"][ ]*[ \t]*\;

I have this file, for example:

['key1'] = 'value1';
                    
['key2']   = 'value2';
['key3'] = 'value3';
            
['key4']  = '<p>text text text text 


text text text text text text text text text                  


  text text text  </p><ul>text
 text text text text text text


 text</p>';

['key5']   = 'value5';

How can I read this text file and make "groups and matches" like this:

Match1: ['key1'] = 'value1';

1. Group1: key1
2. Gropu2: value1

Match2: ['key2'] = 'value2';

1. Group1: key2
2. Gropu2: value2

Match3: ['key3'] = '

text text text text text text text text text text text text text text text text

text text text text text text text text

';

1. Group1: key3
2. Gropu2:

   text text text text

text text text text text text text text text

text text text

text text text text text text text

text

Match4: ['key4'] = 'value4';

1. Group1: key4
2. Gropu2: value4

Answer 1

str = """['key1'] = 'value1';
                    
['key2']   = 'value2';
['key3'] = 'value3';
            
['key4']  = '<p>text text text text 


text text text text text text text text text                  


  text text text  </p><ul>text
 text text text text text text


 text</p>';

['key5']   = 'value5';
"""
re.findall(r"\['(?P<key>\w+)'\]\s*=\s*'(?P<value>[^']+)",str,re.MULTILINE)

results

[('key1', 'value1'), 
('key2', 'value2'), 
('key3', 'value3'), 
('key4', '<p>text text text text \n\n\ntext text text text text text text text text                  \n\n\n  text text text  </p><ul>text\n text text text text text text\n\n\n text</p>'), 
('key5', 'value5')]
