RE: Outputing a node whose value appears only once

Ok, I kind of got your point thus far. In my example,
I had two parents, 'a' and 'c'.  How would I go about
outputing what is in 'a' and not 'c' separately from
outputing what is in 'c' but not 'a'.  In other words,
I want to run my XSL to account for both the unique
values in 'a' as well as the unique values in 'c'.
