How can i get a specific XYZ position from character's animation that still move?

Hi. I'm learning to make simple 3D fighting game for my college. And now im still stuck how to make some simple enemy. Basically i want to make some simple enemy that can predict and avoid the character's attack from its attack's pattern. So far what i think possible is, whenever character trying to attack head by slash from above then enemy see Y position of the character's right hand that above the head's y position so enemy know that gonna be slash, so he will move to right to avoid it. How can i get the hand's position from the animation of character that 'still' process its attack animation?
