Daffodil currently only outputs anything if there are problems (e.g. parse fails, validation error found). Silence means success.
Daffodil does change the exit code depending on success/failure. Zero means success, 1 means failure. So if you want a success message, you can check the return code and print a message when it's zero. I'm not a Windows person, but I /think/ adding this to the end of the bat file should work: if errorlevel 0 echo Succeeded with no validation errors 1>&2 On 4/29/20 1:54 PM, Costello, Roger L. wrote: > Steve wrote: > >> This causes no infoset to be output >> when the parse completes. > > Eek!
