Hello, I wonder, would it be possible to treat empty results as 'potential errors' in Taverna, triggering some kind of error or perhaps a warning message with some tips? When I tried Carsten's xpath example without a namespace the result was empty, not an error. This is correct I now know, but obviously not what I expected at first. My guess is that an empty result is often not what people expect. Just a thought... Cheers, Marco. --
