I have small XSL example which is posing rather large difficulty for me...

Not sure why you think parentheses are needed ... the following-sibling
axis is already in document order.
In the following XML document, I need to be able to query the following:
1) The number of reports which contain an "a" or "b" code where the last
code (in document order) which is either an "a" or "b" is an "a".
Which is to say there is an "a" without a "b" following sibling.
*correct number is 3 *
2) The number of reports which contain an "a" or "b" code where the last
code (in document order) which is either an "a" or "b" is a "b".
Which is to say there is a "b" without an "a" following sibling.
*correct number is 1*
I hope the example below helps.
