Subject: Re: Matching Roman numerals (fwd)
Can someone come up with a (nice) regex that matches only Roman
numerals?
I'm trying to include proper case conversion to title case in a script,
and it should turn a movie title like "HALLOWEEN II" into "Halloween
II", not "Halloween Ii".

Doesn't your email formatter do this out of the box?
Yep. Though only for numerals that are bullets.
The required regex is:
/(M{0,3})(C[MD]|DC{0,3}|C{1,3}|)(X[CL]|LX{0,3}|X{1,3}|)(I[XV]|VI{0,3}|I{
1,3}|)/
or (without captures):
/M{0,3}(?:C[MD]|DC{0,3}|C{1,3}|)(?:X[CL]|LX{0,3}|X{1,3}|)(?:I[XV]|VI{0,3
}|I{1,3}|)/
