If I understand you correctly you want to take a file on your hard
disk and send that to the validator for validation? If so then
WebService::Validator::HTML::W3C is probably what you want. You can
get it from CPAN:


and then the following code should do what you want:

use strict;
use warnings;
use WebService::Validator::HTML::W3C;

my $file = shift;

my $v = WebService::Validator::HTML::W3C->new();
$v->validate_file( $file );
if ($v->is_valid() ) {
    print "$file is valid HTML\n";
} else {
    print "$file is not valid HTML\n";

and then if you save that as validate.pl

./validate.pl file.html

should do what you want.

If you want to actually validate a file without using a web service
then you could have a look at HTML::Validator. I've not used it but it
claims to do the right thing.

Hope that helps
