Chinese Chengyu (Idiom): Refute somebody with his own argument

Question

Is there a Chinese Idiom for

"Refute somebody with his own argument"?

I thought this is not quite the same as "self-contradictory" 自相矛盾.

Thank you.

Maybe 以子之矛，攻子之盾 is the answer, I couldn't find another alternative.

Thank you! Although 自相矛盾 and 以子之矛，攻子之盾 originate from the same story, they don't mean the same things, right? 自相矛盾 means self-contradictory, while 以子之矛，攻子之盾 means "Refute somebody with his own argument." Am I correct?
