Example: Using a ( ( modified yeast ( in PCNA promoter ) ) one-hybrid ( screen ) ) to identify potential ( SRF cofactors ) in cell

Hello Dear Monks,

Is there a nice way to handle recursive split operation in perl? For example, I want to perform a split operation recursively on the above sentence using the parenthesis and space together as the delimiter. So each recursive operation will produce the following:

First pass - each line below may be stored as an array element:
Using a
( modified yeast ( in PCNA promoter ) ) one-hybrid ( screen )
to identify potential
SRF cofactors
in cell

Second pass:
modified yeast ( in PCNA promoter )
one-hybrid
screen

Third pass:
modified yeast
in PCNA promoter

After dividing the sentence recursively, I want to join the split elements to get the original sentence back.

I tried looping using normal split but it does not seem to work.

Any clues? Thanks a lot.
