Unfortunately, I could not get a successful result. The source tree I had supplied with my post was simplified to (besides make it easier for people on the list to read!) illustrate the nature of my problem. When I run your solution against that simplified tree it appears to produce the correct result. However, when I use a slightly more complex source tree (e.g. multiple cities with multiple offices), the result is inconsistent.Yes: that was a bug. In template match="city", the grouping of the office elements included all offices in the current country (rather than the current city).
The problem is noticeable by looking at the transformed U.S. cities. Both cities (Miami and New York) have the same <location> children appearing under their respective <city> parent elements. The problem seems to be the grouping done on offices in different cities in the same country. However, for offices in the same city in the same country, the grouping appears to work just fine (see London results).
I like using the iterative ("for-each") approach that he used, and had rewritten his solution without having to rely on the extension...it seemed to produce similar results, so I would have used it instead if I were able to get the additional grouping level working.No doubt you have noticed I like working with apply-templates, it's a matter of personal taste I guess. I like it because it breaks down the program flow in smaller pieces (modular) and the nesting level is not so deep. But in most cases both approaches are interchangeable. It shouldn't be too difficult to convert my stylesheet to a one-template stylesheet with nested for-each loops.
Good luck! Anton
