Hey guys, I’m trying to select a specific string out of a text, but I’m not a master of regular expressions.
I tried one way, and it starts from the string I want but it matches everything after what I want too.

My regex:

\nSCR((?s).*)(GI|SI)(.*?)\n

Text I’m matching on.

The middle string is selected, it only needs the SCR until the GI line.

    To match from a line starting with SCR to a line starting with GI or SI (inclusive), you would use the following regular expression:

    (?m:^SCR\n(?:^(?!GI|SI).*\n)*(?:GI|SI).*)

    This will:

    • Find the start of a line.
    • Match SCR and a new line.
    • Match all lines not starting with GI or SI.
    • Match the last line, requiring there to be GI or SI (this prevents it from matching to the end of the string if there is no GI or SI.
