RegEx Get string between two strings that has line breaks

by

Use re.S or re.DOTALL flags. Or prepend the regular expression with (?s) to make . matches all character (including newline).

Without the flags, . does not match newline.

(?s)(?<=Test)(.*?)(?=</td>)

Example:

>>> s=""'<td scope="row" align="left">
...       My Class: TEST DATA<br>
...       Test Section: <br>
...       MY SECTION<br>
...       MY SECTION 2<br>
...     </td>'''
>>>
>>> import re
>>> re.findall('(?<=Test)(.*?)(?=</td>)', s)  # without flags
[]
>>> re.findall('(?<=Test)(.*?)(?=</td>)', s, flags=re.S)
[' Section: <br>\n      MY SECTION<br>\n      MY SECTION 2<br>\n    ']
>>> re.findall('(?s)(?<=Test)(.*?)(?=</td>)', s)
[' Section: <br>\n      MY SECTION<br>\n      MY SECTION 2<br>\n    ']
