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;
