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.
