Microsoft uses YACC internally for some projects. YACC is a
table-driven parser. The tables don't do anything by themselves,
without the parser engine. Other tools have been developed that are
more modern than YACC, but Microsoft so far has not shown much
interest in state-of-the-art when it comes to parser generators.

HTML is based on tags and it is doable with table-driven parsers. It
is not simple though.
