Re: Re: Re: Including a 'test only' module in distribution

You still don't need to use a module to do this. All you need is a package which can live quite happily in a script. Here is a HTML::Parser example - Filter inherits from Parser, including its new method as you can see. This works fine within a package structure so you don't need a separate module. It's a rather basic tag filter that only passes specified tags and their content if you were wondering.

package Filter;
use strict;
use base 'HTML::Parser';

my ($filter, $want_it);
my @ok_tags = qw ( h1 h2 h3 h4 p br );
my %ok_tags;
$ok_tags{$_}++ for @ok_tags;
 
sub start {
    my ($self, $tag, $attr, $attrseq, $origtext) = @_;
    if ( exists $ok_tags{$tag}) {
        $filter .= $origtext;
        $want_it = 1;
    } else {
        $want_it = 0;
    } 
}

sub text {
    my ($self, $text) = @_;
    $filter .= $text if $want_it; 
}

sub comment {
    # uncomment to no strip comments
    # my ($self, $comment) = @_;
    # $filter .= "<!-- $comment -->";
}

sub end {
    my ($self, $tag, $origtext) = @_; 
    $filter .= $origtext if exists $ok_tags{$tag};
}

my $parser = new Filter;
my $html = join '', <DATA>;
$parser->parse($html);
$parser->eof;

print $html;
print "\n\n------------------------\n\n";
print $filter;

__DATA__
