How to extract x-y coordinates for more than 1 point at a time?

I would like to extract the x-y coordinates of many (100s) of points at the same time, ideally all selected in a sublayer at one time. I know how to read the coordinates for individual points, but obviously this is not practical. Any ideas? Thanks!
