man HTML::HTML5::Sanity (3): make HTML5 DOM trees less insane

SYNOPSIS

use HTML::HTML5::Parser;
use HTML::HTML5::Sanity;

my $parser = HTML::HTML5::Parser->new;
my $html5_dom = $parser->parse_file('http://example.com/');
my $sane_dom = fix_document($html5_dom);

DESCRIPTION

The Document Object Model (DOM) generated by HTML::HTML5::Parser meets the requirements of the HTML5 spec, but will probably catch a lot of people by surprise.

The main oddity is that elements and attributes which appear to be namespaced are not really. For example, the following element:

  <div xml:lang="fr">...</div>

Looks like it should be parsed so that it has an attribute ``lang'' in the XML namespace. Not so. It will really be parsed as having the attribute ``xml:lang'' in the null namespace.

"fix_document($document)"

  $sane_dom = fix_document($html5_dom);

Returns a modified copy of the DOM and leaving the original DOM unmodified.

"fix_element($element_node, $new_document_node, \%namespaces)"

Don't use this. Not exported.

"fix_attribute($attribute_node, $new_element_node, \%namespaces)"

Don't use this. Not exported.

$HTML::HTML5::Sanity::FIX_LANG_ATTRIBUTES

  $HTML::HTML5::Sanity::FIX_LANG_ATTRIBUTES = 2;
  $sane_dom = fix_document($html5_dom);

If set to 1 (the default), the package will detect invalid values in @lang and @xml:lang, and remove the attribute if it is invalid. If set to 2, it will also attempt to canonicalise the value (e.g. 'EN_GB' will be converted to to 'en-GB'). If set to 0, then the value of language attributes is not checked.
