Re: Regex from a file

[choroba]

You can build the regex from the lines read from the file:

#!/usr/bin/perl
use warnings;
use strict;

open my $REG, '<', 'curse.txt'   or die $!;
(my $regex = join q(), <$REG>) =~ s/\n/|/g;
$regex =~ s/\|$//;

open my $FLT, '>', 'filtered.txt' or die $!;

open my $TXT, '<', 'article.txt' or die $!;
while (<$TXT>) {
    s/$regex/XXX/ig;
    print {$FLT} $_;
}
close $FLT or die $!;

Note: Make yourself familiar with the Scunthorpe_problem.
