Description:

My record is something like this:

News, Product Information, Shopping information, Reference Materials (i.e. dictionaries), Research Materials (i.e. journals, databases), Educational, Hobby / Special Interest (i.e. genealogy, cooking), Financial Material

I'd like to split it by fields, but the commas in the parentheses are a problem.

My initial thought was to use split /,\ [A-Z]/; but would eat away the first letters of the fields.

Better ideas? (maybe the reg exp needs to be craftier, I don't know my brain has turned into jello).

You're on the right track. Use a positive look-ahead in your regex:

@fields = split /, (?=[A-Z])/, $string;
