I'm trying to accomplish the same thing as seen here:
i.e. assuming you have a text like:
<p>something</p>
<!-- OPTIONAL -->
<p class="sdf"> some text</p>
<p> some other text</p>
<!-- OPTIONAL END -->
<p>The end</p>
What is the regex that would match:
<p class="sdf"> some text</p>
<p> some other text</p>
I've setup a live test here using:
<!-- OPTIONAL -->(.*?)<!-- OPTIONAL END -->
but it's not matching correctly. Also the accepted answer on the page didn't work for me. What am I missing?

Multiline option, or the m inline option, enables the regular expression engine to handle an input string that consists of multiple lines. It changes the interpretation of the ^ and $ language elements so that they match the beginning and end of a line, instead of the beginning and end of the input string.
So use \s\S, which will match ALL characters.
The re. MULTILINE flag tells python to make the '^' and '$' special characters match the start or end of any line within a string. Using this flag: >>> match = re.search(r'^It has.
The m flag indicates that a multiline input string should be treated as multiple lines. For example, if m is used, ^ and $ change from matching at only the start or end of the entire string to the start or end of any line within the string. You cannot change this property directly.
Well unfortunately, RegExr is dependent on the JS RegExp implementation, which does not support the option to enable the flag/modifier that you need.
You are looking for the s (DotAll) modifier forcing the dot . to match newline sequences.
If you are using JavaScript, you can use this workaround:
/<!-- OPTIONAL -->([\S\s]*?)<!-- OPTIONAL END -->/
