David,
Fidling around a bit brought me to the XSL you will find below. Some notes
though.
Particularly the part that multiple values have to be added to the same attribute makes it quite
difficult. I have for convenience chosen to add separate class elements to the img content. You
could merge these to a class attribute with a separate transform.
I am very sure this stylesheet can be optimized a lot. It now has to iterate through as many modes
as there are xpaths + 2, which is not good for performance. This could be optimizes if more
knowledge is added to the xpaths.xml. For instance by clustering less and more exact matches into a
group and converting the matches in this group to a choose construct inside a template.
I hope this XSL gives you a jump start or can give you some inspiration for
futher problems..
By the way, I saw your cross post on the dev list and am curious to the STX
solution as well.
Cheers,
Geert
