Hi again I just want to know if they are any way to apply something only if the begin and end element are found ? Because the end element can be optional and this is a problem

If it’s on the same line, mask the begin pattern with a look-ahead to prevent it from matching of the end pattern wouldn’t match.

If it’s on a different line, no.

Cab you give me an exemple please ? I already heard about look-ahead things but I’m french and it’s very hard for me to understand
