Foodeywo:

Regarding your question how $OFH writes to different files. I do it by building an array containing: (1) The name of the regular expression, (2) the regular expression, and (3) the output file handle using this code:

while (<DATA>) {
    . . . create $name, $rex and $FH . . .
    push @rexlist, [ $regex, $name, $FH ];
}

Then as we process the input file, we scan through our regular expressions, and for each one, we pull the regex, name and output file handle out of the array:

while (my $line = <$IFH>) {
    . . .
    # For each regular expression
    for my $r (@rexlist) {
        # Pull the regular expression, name and file handle out of our
+ array
        my ($rex, $name, $OFH) = @$r;
        # If the line matches the regex, write it to the file
        if ($line =~ $rex) {
            print $OFH $line;
        }
    }
    . . .
}
