help in deletion part of a line

[Gary Kline]

	Is there an easier way by sed or ed to remove strings 
	(caight by grep) of the sort:

	part5.chapter2.text-

	where "5" and "2" can be any integer below 10?

	(I know how to delete the *entire* line using ed, but not just
	the first part?

	thanks,

	gary
