regex matching nested parenthesis in python [duplicate]

Question

I'd like to extract all the parameters of these methods with a regex. However, due to the SAL markings, I can't get the nested parenthesis to work correctly. I have these string to parse (multi-lined):

STDMETHOD_(void, Method1)(
_Out_writes_to_(gradientStopsCount, _Inexpressible_("Retrieved through GetGradientStopCount") ) D2D1_GRADIENT_STOP *gradientStops,
UINT32 gradientStopsCount) CONST PURE;

STDMETHOD_(void, Method1)(
_Out_writes_to_(gradientStopsCount, _Inexpressible_("Retrieved through GetGradientStopCount") ) D2D1_GRADIENT_STOP *gradientStops,
UINT32 gradientStopsCount) CONST PURE;

I tried this:

\(((.|\n|\r)*?)\)

But because there are nested parenthesis for the parameters, it won't match properly. Indeed I'd like to extract everything including nested parenthesis of a string like

MyFunc(...anything in here including more parenthesis...)

Is is doable with one single regex?

Be more specific - which part of the string do you want to match? — l'L'l

This will require a recursive regex which supported by regex module of python.Are u willing to use it — vks

May be you can try this

".*?)((.+)).+\;" with s flag to match among several lines.
