Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi There;
How can generate a html report from this text file to show all the unique items on the file? I could use split, but after that I am getting lost trying to count the unique item, like:
I would like to show something like,
Companies: 11<br>
FA: 2 <br>
DI: 2 <br>
DX:1 <br>
Login: 2 <br>

[download]

Thanks for the help!

    Use a hash, something like the following code 

    my %erg = ();
while(<DATA>) {
    my @row = split(/,/,$_);
    ++$erg{$row[3]};
}
print $_ . ': ' . $erg{$_} . '<br />' . "\n" foreach (keys %erg);

    Edit: fixed missing right-curly.
    Edit II: fixed spelling error, removed untested-remark.

      Hi,
      I run the code and it is printing back the total for all the item just like the problem I was having before, but thanks for your effort.
      Result prints:
       48

        Dunno, that's what I get: 

        DI: 3<br />
Not Found: 1<br />
FA: 2<br />
Login: 4<br />
DX: 1<br />

        I got the same here, how would you do if you had to add this numbers up instead of displaying them in order?
