But I need to know how many rows and columns of images were shot. That is say X rows of Y images.Not necessarily.
The rows and columns result from the values of the angle and the focal length.
This values he told precisely - i hope
If the XML doesn't express/reflect/record the correct number of rows and columns to match his image set then it just won't work at all with the Papywizard Import wizard. Likewise the shooting pattern must match is shooting pattern.
FWIW Papywizard in simulation mode computes a grid of 13 rows of 28 images to cover a pano FOV of 270 H x 180 V.
