number one rule to speed up stylesheets: don't use //

//call

causes a search of the entire document (in particular, inside every call
element to see if there are any descendent calls.

/telcoCallList/calls/call

is likely to be much better.

//call[(count(preceding::call

has n^2 performance as for each call you're going back over all the
preceding ones. You just want to select the n'th one out of teh current
list so:

(/telcoCallList/calls/call)[position() = $current_call]


> I get 3 call elements, the first from each calls sub-tree
That's what you are supposed to get, so it looks like they fixed a bug
you shouldn't rely on teh old behaviour. If you want the predicate to
count over the whole expression not just the final step you need () as
above.
