Such a loop isn't complicated.  I've done it when parsing HTML and XML.

You could have it run multiple times--just make sure that when you get the
instr() result on " that you also check the (result - 1) for a \ and omit
the change at that position if it's already a \ from a prior replacement.
You can run it as many times you like then.  

Oh, and make sure that you start your instr() check at your last
double-quote reported position + 1 after substitution, since you've
expanded the string, or it would be less efficient even though it would
still work.
