i need write regex containing not digits [0-9]. how can without explicitly specifying possible charaters in group. possible through lookahead/lookbehind? examples:

034987694 - doesn't match 23984576s9879 - match rtfsdbhkjdfg - match =-0io[-09uhidkbf - match 9347659837564983467 - doesn't match 

^(?!\\d+$).*$
