in reply to Writing a negative regex using =~
G'day John,
Update: My apologies. I thought I'd read your post fully - I must be going blind. You clearly did explain why you wanted to do this. Ignore the crap I wrote. Sorry!
Perhaps if you explained why you wanted to do this, you'd get a better answer. However, to do what you describe, why not just negate the result of =~:
$ perl -Mstrict -Mwarnings -E ' my $x = q{L,0010,8001149805,003,20121015,0600,267,204193,20121015,1300 +,,GBFER,204193}; my $y = q{L,0010,8001149805,003,20121015,0600,267,204193,20121015,1300 +,,XXXXX,204193}; if (! ($x =~ /(?:GBFER|GBFOO)/)) { say "match" } else { say "no match" + } if (! ($y =~ /(?:GBFER|GBFOO)/)) { say "match" } else { say "no match" + } ' no match match
