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.
