in reply to strip JS-comments

Update: Doh! Misconstrued the question to mean remove JavaScript. Leaving the code anyway---it might be useful to someone.

Aristotle helped me with a similar project a while back in another forum. Here's the result. It uses HTML::TokeParser::Simple to do the stripping and works in a very intuitive manner.

#!/usr/bin/perl

use strict;
use HTML::TokeParser::Simple;

use constant SKIP => 0;
use constant COPY => 1;

my $new_folder = 'stripped/';
mkdir $new_folder unless -d $new_folder;
die "Could not create dir $new_folder: $!" unless -d $new_folder;

my $state = COPY;

foreach my $doc ( glob("*.html") ) {

    print "Converting $doc\n";

    my $new_file = "$new_folder$doc";

    my $p = HTML::TokeParser::Simple->new( $doc );

    open OUTFILE, "> $new_file" or die "Cannot open $new_file for writ
+ing: $!";

    while ( my $token = $p->get_token ) {

        if ( $token->is_start_tag ('script') ) {
            $state = SKIP; # stop copying if script
        }

        if ($token->is_end_tag ('script') ) {
            $state = COPY; # start copying again after script
        }

        elsif ( $state == SKIP ) {
            next;
        }


        elsif ( $state == COPY ) {
            print OUTFILE $token->as_is;
        }

   }

    close OUTFILE;
}
