To exclude multiple lines between separators in regex, you can use the following pattern:

1
(?s)start_separator.*?end_separator


Explanation:

  • (?s) enables the DOTALL mode, which allows the . to match newline characters
  • start_separator and end_separator are the separators between which you want to exclude multiple lines
  • .*? matches any character (including newline characters) zero or more times, but in a non-greedy way


Here's an example using this pattern in Python:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
import re

text = """
start_separator
line1
line2
line3
end_separator
"""

pattern = r'(?s)start_separator.*?end_separator'
result = re.search(pattern, text)

if result:
    print(result.group())


In this example, the pattern will match everything between start_separator and end_separator, including multiple lines.
