[flexcoders] Help with RegEx

[marty.pitt]

Hi

Can someone please give me a hand on a RegEx?  (I can't work these
things out for the life of me).

I'm basically trying to return nested groups inside delimeters.

An example we're all famililar with is the simple package / class
structure in Flex:

package foo {
   class bar {
      function stuff {
        ...
      }
    }
}
Given the delimeters oof { and }, I want to be able to return:
function stuff {
...
}

As well as 

class bar {
      function stuff {
        ...
      }
    }

etc., up the chain.

I currently have the following regex working:

{\d*?\D*?}

Which works fine without nesting.  As soon as you introduce nested
elements, it all gets a bit messy.

any help would be greatly appreciated.

Cheers

Marty
