Daffodil has been integrated with the Calabash XProc software to allow Daffodil to parse non-XML data and flow it into an XProc pipeline.
Small examples are included which have XProc steps that run Daffodil to parse non-XML data.
This can be downloaded via:
git clone https://opensource.ncsa.illinois.edu/stash/scm/dfdl/daffodil-calabash-extension.git
See the BUILDING.txt and README.txt files for instructions.
