Sorry, I need to 'scan' it. I have been playing around with similar 
regexps, but they did not work out. E.g. also yours:

irb(main):007:0> text = '.... #begin aaaa end bbb } ccc end ddd'
=> ".... #begin aaaa end bbb } ccc end ddd"
irb(main):008:0> n = 2
=> 2
irb(main):009:0> text.scan(/#begin(.*(\}|end)){#{n}}/m)
=> [[" ccc end", "end"]]

does not work with scan...

Cheers,
Peter
