(sorry if this is a repost - i did not see my last one come onto the list)

>   Bob  | 2 X Days | 1 Y Day | 1 Z Day
>   Sam | 3 X Days | 2 Y Day | 1 Z Day
> 
> I have been doing this using the count() function, counting employee/holiday[@type='X'] for example.
> 
> At the end of each department I need to total the number of X days. I am hoping there is a nice elegant way to do this but I do not know how. I do know I cannot incremement a variable because I tried this and also read it.
