+=head1 NAME
+
+HTML::Filter - Filter HTML text through the parser
+
+=head1 NOTE
+
+B<This module is deprecated.> The C<HTML::Parser> now provides the
+functionally of C<HTML::Filter> much more efficiently with the the
+C<default> handler.
+
+=head1 SYNOPSIS
+
+ require HTML::Filter;
+ $p = HTML::Filter->new->parse_file("index.html");
+
+=head1 DESCRIPTION
+
+C<HTML::Filter> is an HTML parser that by default prints the
+original text of each HTML element (a slow version of cat(1) basically).
+The callback methods may be overridden to modify the filtering for some
+HTML elements and you can override output() method which is called to
+print the HTML text.
+
+C<HTML::Filter> is a subclass of C<HTML::Parser>. This means that
+the document should be given to the parser by calling the $p->parse()
+or $p->parse_file() methods.
+
+=head1 EXAMPLES
+
+The first example is a filter that will remove all comments from an
+HTML file.  This is achieved by simply overriding the comment method
+to do nothing.
+
+  package CommentStripper;
+  require HTML::Filter;
+  @ISA=qw(HTML::Filter);
+  sub comment { }  # ignore comments
+
+The second example shows a filter that will remove any E<lt>TABLE>s
+found in the HTML file.  We specialize the start() and end() methods
+to count table tags and then make output not happen when inside a
+table.
+
+  package TableStripper;
+  require HTML::Filter;
+  @ISA=qw(HTML::Filter);
+  sub start
+  {
+     my $self = shift;
+     $self->{table_seen}++ if $_[0] eq "table";
+     $self->SUPER::start(@_);
+  }
+
+  sub end
+  {
+     my $self = shift;
+     $self->SUPER::end(@_);
+     $self->{table_seen}-- if $_[0] eq "table";
+  }
+
+  sub output
+  {
+      my $self = shift;
+      unless ($self->{table_seen}) {
+         $self->SUPER::output(@_);
+      }
+  }
+
+If you want to collect the parsed text internally you might want to do
+something like this:
+
+  package FilterIntoString;
+  require HTML::Filter;
+  @ISA=qw(HTML::Filter);
+  sub output { push(@{$_[0]->{fhtml}}, $_[1]) }
+  sub filtered_html { join("", @{$_[0]->{fhtml}}) }
