NAME

       HTML::HTML5::Sanity - 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.
