separated_list does not reflect your desired syntax, as far as I can see. But then, neither does using intervalue for the limits of the interval.

separated_list is not correct because it is used for an list of any positive number of elements separated by a delimiter. In particular, separated_list(TWOPoints, intervalue) will not just match 1..4, but also 1, and 1..4..7, among other things. Those other things include nested intervalues, such as 2..[4..7], which seems unlikely to be a desired construct (although since I don't know what your language looks like, perhaps it is).

You seem to be using separated_list in the mistaken belief that it is the only way to turn the reduction into an OCanl list. That's not true, since you have the full power of OCaml available to you; you could write that production as

FIND() will identify where a particular character first appears in a string. You can use this to find the parentheses in your text strings. Then plug those numbers into MID to extract the strings you want:
