parse HTML reliably

 HTML::HTML5::Parser is an HTML parser, similar to the non-CPAN module
 Whatpm::HTML with some changes including:
 .
  * Provides an XML::LibXML-like DOM interface. If you usually use
    XML::LibXML's DOM parser, this should be a drop-in solution for tag
    soup HTML.
 .
  * Constructs an XML::LibXML::Document as the result of parsing.
 .
  * Via bundling and modifications, removed external dependencies on
    non-CPAN packages.
