I very much appreciate Wayback Machine's work and would like to support them by offering our SGML software for free (see contact info on http://sgml.io http://sgml.io or PM). SGML can be used as swiss army knife to perform all kinds of difficult HTML parsing, manipulation, and preservation tasks since it is using classic DTD grammars for your HTML flavor at hand, rather than having a particular HTML grammar hardcoded. For example, see our HTML 5.1 DTD at [1] (which can be used with any SGML software freely anyway). In today's dark age of the web, we're loosing content daily as classic web sites are shutting down.
