Jason,
Here is a possible solution for C2 (don't know which version you are using)
The sorting part is the most difficult part. If it is possible to let the
searchengine sort the results, you should go for this approach. Otherwise
you have to write a transformer which does the sorting, but this won't be
possible without storing the result in an intermediate datastructure, which
you have to sort and which you have to stream into SAX events again
afterwards.
When this is done, you can reuse some transformers in C2: FilterTransformer,
WriteDOMSessionTransformer and ReadDOMSessionTransformer. See the
documentation for SQLTransformer for more info on these...
