Okay, now I see that page source is:

  https://github.com/D-Programming-Language/dlang.org/edit/master/grammar.dd

and it is a Ddoc document ource file.

According to what little I know, that is THE source document which
could be used to generate input formats for various parsers.  Is such
a filter available?  If not, would such a filter for that be useful?
