cumulative sum

I have two shapefiles, one is a polyline (Oil Pipeline) and the other is a polygon (land parcels). What I want to is too have a field display the distance (in km) from the start of pipeline when it crosses into a polygon and another when it leaves the polygon. To make things a litte harder in some instances the pipeline crosses then leaves, then re-crosses the same polygon again, I'm only interested in when it first enters the polygon and when it finally leaves.

Any help at all would be really appreciated.
