I tried to parse the following mail body:
=== ABSTRACT START ===
Text takes place here.
=== ABSTRACT ENDE ===
Using the following regex:
=== ABSTRACT START ===\s(.*)\s=== ABSTRACT ENDE ===
But this does not match. However, writing the message in a single line works. Do you have implemented the "/s"-Modifier? Is there any alternative?
Trying the regex online here https://regex101.com/ works perfect.
