I know there must be a (much) easier way to do this, but the following
code will do the job:

######
import string, re

the_string = r"""aaa(foo)bbb(bar)asdfsadf
ee(g)(adfsadf)ddd xxxx"""

elements = string.split(the_string, ')')

x = re.compile(r'\((.+)$', re.M | re.S)

for element in elements:
   z = x.search(element)
   if z: print z.group(1)
######

On the other hand, if you do it like this, you don't even need Regular
Expressions at all... The string module will be sufficient:

for element in elements:
    z = string.find(element, "(")
    if z != -1:
        print element[z+1:]


Hope this helps,
Matthias
