Re^2: Regex help

Thank you everyone, all methods worked great :) I do have one slight niggle though, If the string contains the value AA1X32ALFC60JT8 then can this entire row including the /dp be excluded? e.g can -plastic-protector-AA1X32ALFC60JT8/dp/B00074658 be removed from the results? Thank you :)

See the specific grep-map code in my other answer. For this requirement, you would simply add a negative match to the grep block:

my @ids = grep { defined $_ && $_ !~ m{AA1X32ALFC60JT8} } map { match_
+id($_) } @lines_from_file;
