Well, grep is not going to work too well anymore, but extracting a
specific field from an entry is going to be beyond the competence of
simple grep/sed tools anyway if we allow column default substitutions.

I think a fairer question is "can you do that in a one-liner Perl script",
which seems like it might be achievable given an appropriate choice of
data markup language.
