Re: Newbie question: Incrementing the position in the

I have a set of XML outputs from a database which splits a table into individual cells -

test-plan/object/cell N
test-plan/object/cell N+1
test-plan/object/cell N+2
test-plan/object/cell N+3

I can search to find cell N. I'd like to be able to print cell N, cell N+1, cell N+2 ... all at once and then when XSL goes back
to searching (via a For) through the tree, it skips N+1, N+2 etc. (basically does a table row and then skips to the beginning of
the next row). Without entering another XML attribute into our DB to indicate beginning and end of rows... How do I increment
the position, moving from object/cell N to object/cell N+1 midstream?
