Then don't use a regular expression. 

There's a quote by Brian Kernighan that “Debugging is twice as hard as
writing the code in the first place. Therefore, if you write the code
as cleverly as possible, you are, by definition, not smart enough to
debug it.”

In other words, if it's not quickly obvious how to write a regular
expression that does what you want, use something else. Your
maintenance programmers (often your six-month older self) will thank
you.

From the description you've given of the problem, I would think that
your best bet is to parse your input as a CSV, do the required
changes, and write it back into a CSV. Easier to write and easier to
read than a dose of line noise.
