Hello Henri. Maybe you right,and regexp is not good way. May be exists 
ways to redefine $$ and $ in lualatex,because i want,that for formulas 
with $$ and $ inserted actualtext,so i decided use lua callbacks,to 
replace it in [] or (),because in this redefined commands i do insertion 
of actualtext in formula. May be you know another ways,how insert 
actualtext in formulas with $$ or $ (actualtext must contains tex 
notation of this formula)? Thanks very mutch everybody for the any help 
and any ideas.
