Summing up 3 specifically named nodes under Records/Record and summing
them only if they are numbers.

Current XSL===>

sum(Records/Record/*[name(.) = 'AContribution' and number(.) =
number(.) or name(.) = 'BContribution' and number(.) = number(.) or
name(.) = 'CContribution' and number(.) = number(.)])

sum( ( Records/Record/AContribution | Records/Record/BContribution
     | Records/Record/CContribution )[number(.)=number(.)] )

I'm just trying to reduce redundancy.

You don't say *where* you want to reduce
redundancy ... the above syntactically reduces
your expression ... I cannot comment on the speed
as that would be dependent on your processor so I
don't think the question can be answered in that way.
