Dear Monks, I am working with my Perl program on csv files. These csv files contained some information lines, gathered in blocks.

Everything was OK until I made some modifications in my files and then there was some ";" instead of the blank lines. Thus my code did not work.

I don't know how to modify it so that even if some ";" appear (several per line), it will still work.

Here is a part of my code 

while(my $line = <$FILE>){
    $line =~ s/\s+$//;
    if ($line =~ /(^\w+)/){
    ...
    }
}
