This isn't going to get them all; it says to match (between word
boundaries) "I" or "II" or any three non-newlines. So it will catch
"I", "II", "III", and "VII". It will also catch "I" where it's a
pronoun (assuming this is an english text file), and any three-letter
words/constructs.
I'm sorry, that regex wasn't meant to be taken literally. I just didn't
feel the need to reproduce the alternations *again*.
I would trysomething like this:
s/\bI(?:I+|V|X)?|VI*|XI*\b//
This will get rid of the "I" in "Ishmael". Your \b anchors aren't
effective on the *entire* pattern. You're matching
\bI(?:I+|V|X)?
or
VI*
or
XI*\b
The regex I would use would probably be
/\b(?:I{1,3}|IV|VI{0,3}|I?X)\b/
