NAME

HTML::StripScripts::Parser - XSS filter using HTML::Parser

SYNOPSIS

  use HTML::StripScripts::Parser();

  my $hss = HTML::StripScripts::Parser->new(

       {
           Context => 'Document',       ## HTML::StripScripts configuration
           Rules   => { ... },
       },

       strict_comment => 1,             ## HTML::Parser options
       strict_names   => 1,

  );

  $hss->parse_file("foo.html");

  print $hss->filtered_document;

  OR

  print $hss->filter_html($html);

DESCRIPTION

This class provides an easy interface to HTML::StripScripts, using HTML::Parser to parse the HTML.

See HTML::Parser for details of how to customise how the raw HTML is parsed into tags, and HTML::StripScripts for details of how to customise the way those tags are filtered.

CONSTRUCTORS

new ( {CONFIG}, [PARSER_OPTIONS] )

Creates a new HTML::StripScripts::Parser object.

The CONFIG parameter has the same semantics as the CONFIG parameter to the HTML::StripScripts constructor.

Any PARSER_OPTIONS supplied will be passed on to the HTML::Parser init method, allowing you to influence the way the input is parsed.

You cannot use PARSER_OPTIONS to set the HTML::Parser event handlers (see "Events" in HTML::Parser) since HTML::StripScripts::Parser uses all of the event hooks itself. However, you can use Rules (see "Rules" in HTML::StripScripts) to customise the handling of all tags and attributes.

METHODS

See HTML::Parser for input methods, HTML::StripScripts for output methods.

filter_html()

filter_html() is a convenience method for filtering HTML already loaded into a scalar variable. It combines calls to HTML::Parser::parse(), HTML::Parser::eof() and HTML::StripScripts::filtered_document().

    $filtered_html = $hss->filter_html($html);

SUBCLASSING

The HTML::StripScripts::Parser class is subclassable. Filter objects are plain hashes. The hss_init() method takes the same arguments as new(), and calls the initialization methods of both HTML::StripScripts and HTML::Parser.

See "SUBCLASSING" in HTML::StripScripts and "SUBCLASSING" in HTML::Parser.
