How to extract parts of g code using matlab

I want to obtain is a script capable of loading the g code and dividing it into a structure with cells containing the individual commands: I want to find the strings in which the outer contour of all layers is drawn, initialized by; TYPE: WALL-OUTER, as a result of which all commands containing the token G1 at the beginning of the command are stored, followed by the X Y Z E coordinates of displacement and possibly also from F. Then, also commands with the token G0 are stored.
