getting animation key information

Dear Team

i have an animation from frame 0 to animationRange.end let s say.

i am loopinp over the keyframe and getting rotation matrix but i wish to have the position any idea ?
for f = animationRange.start to animationRange.end do
(
-- set MAX time slider to current frame
sliderTime = f
local tmR = $Box002.transform.rotationPart
)

thanks in advance
