典型例题
---You were brave enough to raise objections at the meeting.
---Well,now I regret ___ that.
A.to do B.to be doing C.to have done D.having done
答案：D.regret having done sth.对已发生的事感到遗憾.regret to do sth.对将要做的事感到遗憾.本题为对已说的话感到后悔,因此选D.

你记错了:regret to do sth遗憾没有做过某事
regret doing sth是抱歉做过某事

regret doing 是后悔做了某事，根据句子中的意思是我不后悔告诉他我的想法，即使这样会伤害她
didn't regret having told her是不后悔已经告诉她了

就算不知道regret to do sth与regret doing sth的区别，仅从hurt就可以判断选C，因为hurt的过去式为hurt。
regret having told her在此处应理解为“并不后悔告诉她”。
