remove polyline intersect

I have a couple of polyline shapefiles (the polylines are all closed), and I need to delete the polyline segment from one file that intersects with the other so that I'm left with open polylines (see attachment: remove the section of the black polyline that is coincident with the yellow polyline). Other than manually splitting and deleting, does anyone have an idea on how to do it all at once? Merging the intersect back to the shapefile with the intention of deleting won't work.
