Using the XSLT-19990813 Working Draft, you would use predicates in the fashion shown in the example below. Note that I am not using variables where I could, but I'm hoping the way I've coded it illustrates what you need.

I'm asking for a count of all ancestor elements whose name is equal to the name of the parent of the current element ... which is what I think you are asking for.

I hope this helps.
