The question here is: What _can't_ happen? For instance, what happens
if Fred's name contains a greater-than symbol, or a caret?

If those absolutely cannot happen, your parser can be fairly
straight-forward. Just put together some basic splitting (maybe a
regex), and then split on the caret inside that. Otherwise, you may
need a more stateful parser.
