--> Mathieu.
I just finished readind your answer to Vincent.
I guess you were thinking about an other problem (huge binary fields) ...
DS  (for Decimal String) are never very long .
(just
PrintFile dirin=gdcmData | grep DS
)
It's always something like Image Orientation (Patient).

I'm gonna add a very simple method, like :
std::vector <double> File::GetDSValue(uint16_t group,uint16_t element);
