Assuming the outer function name is only word characters and inner 
function is word characters or the dollar sign, you can search for: 
\w+\(([\w$]+\(.*?\))\)

Then replace with $1 (capture register one).

I would recommend that you study regular expressions and also 
TextMate’s format strings, for the more TextMate specific stuff, here 
are some useful links:
