-
-HTML::Scrubber - Perl extension for scrubbing/sanitizing html
-
-=head1 VERSION
-
-version 0.15
-
-=head1 SYNOPSIS
-
-    use HTML::Scrubber;
-
-    my $scrubber = HTML::Scrubber->new( allow => [ qw[ p b i u hr br ] ] );
-    print $scrubber->scrub('<p><b>bold</b> <em>missing</em></p>');
-    # output is: <p><b>bold</b> </p>
-
-    # more complex input
-    my $html = q[
-    <style type="text/css"> BAD { background: #666; color: #666;} </style>
-    <script language="javascript"> alert("Hello, I am EVIL!");    </script>
-    <HR>
-        a   => <a href=1>link </a>
-        br  => <br>
-        b   => <B> bold </B>
-        u   => <U> UNDERLINE </U>
-    ];
-
-    print $scrubber->scrub($html);
-
-    $scrubber->deny( qw[ p b i u hr br ] );
-
-    print $scrubber->scrub($html);
-
-=head1 DESCRIPTION
-
-If you want to "scrub" or "sanitize" html input in a reliable and flexible
-fashion, then this module is for you.
-
-I wasn't satisfied with HTML::Sanitizer because it is based on
-HTML::TreeBuilder, so I thought I'd write something similar that works directly
-with HTML::Parser.
-
-=head1 METHODS
-
-First a note on documentation: just study the L<EXAMPLE|"EXAMPLE"> below. It's
-all the documentation you could need
-
-Also, be sure to read all the comments as well as L<How does it work?|"How does
-it work?">.
-
-If you're new to perl, good luck to you.
-
-=head2 comment
-
-    warn "comments are  ", $p->comment ? 'allowed' : 'not allowed';
-    $p->comment(0);  # off by default
-
-=head2 process
-
-    warn "process instructions are  ", $p->process ? 'allowed' : 'not allowed';
-    $p->process(0);  # off by default
-
-=head2 script
-
-    warn "script tags (and everything in between) are supressed"
-        if $p->script;      # off by default
-    $p->script( 0 || 1 );
-
-B<**> Please note that this is implemented using HTML::Parser's ignore_elements
-function, so if C<script> is set to true, all script tags encountered will be
-validated like all other tags.
-
-=head2 style
-
-    warn "style tags (and everything in between) are supressed"
-        if $p->style;       # off by default
-    $p->style( 0 || 1 );
-
-B<**> Please note that this is implemented using HTML::Parser's ignore_elements
-function, so if C<style> is set to true, all style tags encountered will be
-validated like all other tags.
-
-=head2 allow
-
-    $p->allow(qw[ t a g s ]);
-
-=head2 deny
-
-    $p->deny(qw[ t a g s ]);
-
-=head2 rules
-
-    $p->rules(
-        img => {
-            src => qr{^(?!http://)}i, # only relative image links allowed
-            alt => 1,                 # alt attribute allowed
-            '*' => 0,                 # deny all other attributes
-        },
-        a => {
-            href => sub { ... },      # check or adjust with a callback
-        },
-        b => 1,
-        ...
-    );
-
-Updates set of attribute rules. Each rule can be 1/0, regular expression or a
-callback. Values longer than 1 char are treated as regexps. Callback is called
-with the following arguments: this object, tag name, attribute name and
-attribute value, should return empty list to drop attribute, C<undef> to keep
-it without value or a new scalar value.
-
-=head2 default
-
-    print "default is ", $p->default();
-    $p->default(1);      # allow tags by default
-    $p->default(
-        undef,           # don't change
-        {                # default attribute rules
-            '*' => 1,    # allow attributes by default
-        }
-    );
-
-=head2 scrub_file
-
-    $html = $scrubber->scrub_file('foo.html');   ## returns giant string
-    die "Eeek $!" unless defined $html;  ## opening foo.html may have failed
-    $scrubber->scrub_file('foo.html', 'new.html') or die "Eeek $!";
-    $scrubber->scrub_file('foo.html', *STDOUT)
-        or die "Eeek $!"
-            if fileno STDOUT;
-
-=head2 scrub
-
-    print $scrubber->scrub($html);  ## returns giant string
-    $scrubber->scrub($html, 'new.html') or die "Eeek $!";
-    $scrubber->scrub($html', *STDOUT)
-        or die "Eeek $!"
-            if fileno STDOUT;
-
-=for comment _out
-    $scrubber->_out(*STDOUT) if fileno STDOUT;
-    $scrubber->_out('foo.html') or die "eeek $!";
-
-=for comment _validate
-Uses $self->{_rules} to do attribute validation.
-Takes tag, rule('_' || $tag), attrref.
-
-=for comment _scrub_str
-
-I<default> handler, used by both _scrub and _scrub_fh Moved all the common code
-(basically all of it) into a single routine for ease of maintenance
-
-=for comment _scrub_fh
-
-I<default> handler, does the scrubbing if we're scrubbing out to a file. Now
-calls _scrub_str and pushes that out to a file.
-
-=for comment _scrub
-
-I<default> handler, does the scrubbing if we're returning a giant string. Now
-calls _scrub_str and appends that to the output string.
-
-=head1 How does it work?
-
-When a tag is encountered, HTML::Scrubber allows/denies the tag using the
-explicit rule if one exists.
-
-If no explicit rule exists, Scrubber applies the default rule.
-
-If an explicit rule exists, but it's a simple rule(1), the default attribute
-rule is applied.
-

-=head2 FUN
-
-If you have Test::Inline (and you've installed HTML::Scrubber), try
-
-    pod2test Scrubber.pm >scrubber.t
-    perl scrubber.t
-
-=head1 SEE ALSO
-
-L<HTML::Parser>, L<Test::Inline>.
-
-The C<HTML::Sanitizer> module is no longer available on CPAN.
-
-=head1 VERSION REQUIREMENTS
-
-As of version 0.14 I have added a perl minimum version requirement of 5.8. This
-is basically due to failures on the smokers perl 5.6 installations - which
-appears to be down to installation mechanisms and requirements.
-
-Since I don't want to spend the time supporting a version that is so old (and
-may not work for reasons on UTF support etc), I have added a C<use 5.008;> to
-the main module.
-
-If this is problematic I am very willing to accept patches to fix this up,
-although I do not personally see a good reason to support a release that has
-been obsolete for 13 years.
-
-=head1 CONTRIBUTING
-
-If you want to contribute to the development of this module, the code is on
-L<GitHub|http://github.com/nigelm/html-scrubber>. You'll need a perl
-environment with L<Dist::Zilla>, and if you're just getting started, there's
-some documentation on using Vagrant and Perlbrew
-L<here|http://mrcaron.github.io/2015/03/06/Perl-CPAN-Pull-Request.html>.
-
-There is now a C<.perltidyrc> and a <.tidyallrc> file within the respository
-for the standard perltidy settings used - I will apply these before new
-releases.  Please do not let formatting prevent you from sending in patches etc
-- this can be sorted out as part of the release process.  Info on C<tidyall>
-can be found at
-L<https://metacpan.org/pod/distribution/Code-TidyAll/bin/tidyall>.
-
-=head1 INSTALLATION
-
-See perlmodinstall for information and options on installing Perl modules.
-
-=head1 BUGS AND LIMITATIONS
-
-You can make new bug reports, and view existing ones, through the
-web interface at L<http://rt.cpan.org/Public/Dist/Display.html?Name=HTML-Scrubber>.
-
-=head1 AVAILABILITY
-
-The project homepage is L<https://metacpan.org/release/HTML-Scrubber>.
-
-The latest version of this module is available from the Comprehensive Perl
-Archive Network (CPAN). Visit L<http://www.perl.com/CPAN/> to find a CPAN
-site near you, or see L<https://metacpan.org/module/HTML::Scrubber/>.
