that I want to split by commas -- but I need to igno

Answer 1

Rather than use lookahead and other crazy regex, just pull out the quotes first. That is, for every quote grouping, replace that grouping with __IDENTIFIER_1 or some other indicator, and map that grouping to a map of string,string.

After you split on comma, replace all mapped identifiers with the original string values.
