Hello midiperl,

I also tried using a while loop to read the file in line by line and match each line against the combined regex - but that did not capture both patterns either.

Well, since you specify that The patterns are not on the same line of text, the following approach also works:

use strict;
use warnings;
use feature 'say';

while (<DATA>)
{
    say $1 if /#augment:(?:A|B)(.*)/;
}

__DATA__
First line of the file used for filler
#augment:A Something One
Another line of text for filler
#augment:B Something Two
Last line of the file used for filler

Output:

13:20 >perl 1350_SoPW.pl
 Something One
 Something Two

13:21 >

P.S. Please fix the formatting of your post by changing <\code> to </code>.

Hope that helps,
