That looks pretty good, but it doesn't deal with multiple levels of parens. I think Text::Balanced is really the better solution.

... but it doesn't deal with multiple levels of parens. Coding now to deal with nested parens would be solving a problem that hasn't been presented. There might or might not be nested parens in the data. I'd wait for the "customer" to clarify their requirements before hitting this with a larger hammer. YMMV.	[reply]
