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:
...
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.
