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.
