Hi you two I give you some nice raw spaghetti code to filter your tags, save as TagFilter.h in your browser’s profile folder, adjust as preferred:

use HTML::TagFilter;
    my $tf = new HTML::TagFilter;
    my $clean_html = $tf->filter($dirty_html);
    
    # or
    
    my $tf = HTML::TagFilter->new(
        allow=>{...}, 
        deny=>{...}, 
        log_rejects => 1, 
        strip_comments => 1, 
        echo => 1,
        verbose => 1,
        skip_xss_protection => 1,
        skip_entification => 1,
        skip_mailto_entification => 1,
        xss_risky_attributes => [...],
        xss_permitted_protocols => [...],
        xss_allow_local_links => 1,
    );
    
    # or

    my $tf = HTML::TagFilter->new(
        on_finish_document =>sub {
                return "\n<p>" . $self->report . "</p>\n";
        }, 
    );
    
    $tf->parse($some_html);
    $tf->parse($more_html);
    my $clean_html = $tf->output;
    my $cleaning_summary = $tf->report;
    my @tags_removed = $tf->report;
    my $error_log = $tf->error;
my $tf = HTML::TagFilter->new(
    log_rejects => 1,
    strip_comments => 1,
    echo => 1,
    verbose => 1,
    skip_xss_protection => 1,
    skip_ltgt_entification => 1,
    skip_mailto_entification => 1,
  );
$self->xss_risky_attributes( qw(your list of attributes) );
$self->allow_tags({ p => { 'any' });
$self->allow_tags({ p => { none => [] });
$self->allow_tags({ a => { any => [] } });
    $self->deny_tags({ a => { onClick => [] } });
my $filter = HTML::TagFilter->new(
        on_start_document => sub {
                my ($self, $rawtext) = @_;
                $self->{_tag_stack} = [];
                return;
        },
        on_open_tag => sub {
                my ($self, $tag, $attributes, $sequence) = @_;
                push @{ $self->{_tag_stack} }, $$tag unless grep {$_ eq $$tag} qw(img br hr meta link);
                return;
        },
        on_close_tag => sub {
                my ($self, $tag) = @_;
                unless (@{ $self->{_tag_stack} } && grep {$_ eq $$tag} @{ $self->{_tag_stack} }) {
                        undef ${ $tag };
                        return;

                my @unclosed;

                        return join '', map "</$_>", @unclosed if $lasttag eq $$tag;
                        push @unclosed, $lasttag;
                }
        },
        on_finish_document => sub {
                my ($self, $cleantext) = @_;
                return join '', map "</$_>", reverse @{ $self->{_tag_stack} };
        },
  );
 sub on_open_tag {
        my ($self, $tag, $attributes, $sequence) = @_;
        $$tag = 'strong' if $$tag eq 'b';
  }

  sub on_close_tag {
        my ($self, $tag) = @_;
        $$tag = 'strong' if $$tag eq 'b';
  }
 print $tf->filter( $pages{$_} ) for keys %pages;

I’m sorry but I don’t quite understand what this code does could you clarify it ?
