What Jade doesn't support is the query *feature* of the style language, which means that you can't use query construction rules. However, you can get around this by replacing the normal construction rules with a single default rule that uses a COND expression to apply queries to the current node, e.g.: (default (cond ((query-function-one (current-node)) (make x)) ((query-function-two (current-node)) (make y)) (else (process-children))) It's ham fisted, but it works. I don't know how efficient it is (probably not very). Cheers, Eliot -- <Address HyTime=bibloc> W.
