in reply to Advanced replace function

You may be looking for the /g option to s///:

my $str="abc t[poop1] def [doop2] [woop3] xyz"; $str =~ s/\[.*?\]/~~/g; print "$str\n"; __END__ abc t~~ def ~~ ~~ xyz

    There was nothing about newlines being disallowed in the brackets. The following is faster and more likely to match correctly:
    s/\[.*?\]/~~/sg

    But that's risky, especially if you use it a larger pattern. The /.*?/ could match a "[" or a "]". That's obviously undesirable. The following pattern avoids that problem:

    s/\[[^\[\]]*\]/~~/g;

[Corion]: marto: Well, I think they go a tour every two years and I think it's hard to even get a connection with the crowd at a 20k people concert... But maybe after this time I'll stop too ;)
[Corion]: I still have to see the Pet Shop Boys live before they stop touring at all
[marto]: yeah, I think that as a group creatively they're done. I can understand how it'd be hard to stop the process, album/tour, album/tour, if that's pretty much all you've ever done :)
[marto]: Corion yes I saw them Pandemonium_Tour
[Corion]: marto: Yeah, and I doubt that they'll ever get back to something like Violator/Songs of Faith and Devotion - it would either alienate their "regular" crowd, or be "too much Violator" ;)
LanX needs to see Freddy Mercury'
[Corion]: marto: Yeah, I have that on DVD even, and I missed them last year because I was in London at the time ironically ;)
[marto]: put me in the mood to listen to this now :)
[Corion]: LanX: Well, grab a shovel :)
[Corion]: Kraftwerk also are still touring (well, only Ralf Hütter and Florian Schneider), but I'm too tight fisted to spend EUR 150+ for standing around two hours ;)
