Yes.

In the new input, the DESCRIPTION_ITEM elements are ordered such that
all the cells for a particular row are clustered together. The first
of each cluster is the one whose col attribute has the value 0. The
rest of the cells in the row are the next N DESCRIPTION_ITEMs, where N
is the number of columns minus 1. One way you could select them is:

  . | following-sibling::DESCRIPTION_ITEM[position() &lt; $ncols]

Another way you could select them would be:

  ../DESCRIPTION_ITEM[@row = current()/@row]

The latter is probably better simply because if they change the order
on you again it will still work. On the other hand, the former
involves less node visits, so will probably be faster with large
tables.
