in reply to using bits to print part of a string

Hi all,

I like choroba's solution. Therefor a ++. I just want to show my solution to prove the TMTOWTDI of perl. ;-)

my @strings = ( 'Abcderd', 'dkdnnjn', 'ddjfdjk', 'c,oktnx', ); my $mask = '0100110'; my $regex = '^' . join('', map { $_ ? '(.)' : '.' } split //, $mask) . + '$'; foreach my $string (@strings) { my $result = join '', ($string =~ m/$regex/o); print $result, "\n"; }

Best regards

[ambrus]: Sometimes it's easier to just match elements in ways other than xpath, like directly with perl code.
[marto]: this is a cheap hack, a script that doesn't need to run for long, using WWW::Mechanize:: Firefox to drive some awful interface.
[marto]: if it were anything more serious I'd spend more time looking into it properly :P
