Question

I am trying to remove text that is within parentheses (along with the parentheses themselves) but am having trouble with the scenario where there are parentheses within parentheses. This is the method I am using (in Ruby):

sentence.gsub(/\(.*?\)/, "") 

and that works fine until I have a sentence such as:

"This is (a test (string))"

Then the above chokes. Anyone have any idea how to do this? I am completely stumped.

One approch is to replace the parenthetical groups from the inside out:

x = string.dup
while x.gsub!(/\([^()]*\)/,""); end
x
