It comes up so often that it MUST be a reasonable requirement. If you want to do it in less than 35mins, try SAXON's group-by construct. (It's proprietary, though with extension elements becoming respectable it will soon become more of a "standard extension" than a "proprietary extension" - not that this makes any practical difference!) The SAXON construct doesn't solve the problem by giving you sorted axes, it does it by allowing you to write code that in effect allows you to add a layer of hierarchy to a nodeset, so you can say for each group of consecutive nodes with the same value of EXPR do -- start of group processing ---- for each node withing the group do ------ process the node ---- end -- end of group processing end (It's puzzled me for a while that the design of XSL seems to have learnt very little from 25 years of experience in designing report writers!)
