List problem

Hello, I have a problem that may seem simple, but I am currently unable to solve it.

I have several points and a number of closed curves, and I need to determine which points are inside which curves. After that, I would like to separate the curves into two categories: those that contain points and those that do not.
I have completed the first part, and I now have the curves that include the points.
Here is what I have accomplished.


How can I find the curves that do not include a specific point?

CrossReference is not the best for this case.

Use datatrees:

notice the arrows… graft and flatten

Thank you very much.

How I will also get the points with this way that are inside the curves. Not all points are inside curves.
