[Closed] How to do a spline boolean?

Hey can anyone help me figure out how to boolean two splines, like subtracting the second from the first? I figure the way I could go about it is maybe by copying all of the positions of the knots and tangents for the parts that stay the same, adding new knots on the overlapping segments, and deleting segments that are to be removed. So first I would probably need to figure out how to check which parts of the second shape are inside the first. Any help would be appreciated thanks!
