No, I don't think it can handle SGML. I'm not familiar with SGML, but my
understanding is that a lot of its tags are quite different than HTML's.
Also, the http server would likely assign a different content-type to
SGML documents, so htdig won't even attempt to parse them.
Meta tags in HTML are supported by htdig.

External parsers must definitely be htdig aware. Their output must adhere
to the format specified in the documentation. See
http://www.htdig.org/attrs.html#external_parsers
for details. The parse_doc.pl script, and its earlier versions as perl
and shell scripts, is the only external parser around that's publically
available, as far as I know. Someone on the list can correct me if I'm
wrong. parse_doc.pl is also a good starting point if you want to set
up an interface between htdig and any number of more Unix-like document
parsers. Any filter that can extract plain text from a document can
easily be plugged into this script, and it handles the generation of
records for htdig.
