Daffodil is available as two Apache NiFi processors called DaffodilParse and DaffodilUnparse. The source for the processors is available from the NCSA opensource Git repository:
git clone https://opensource.ncsa.illinois.edu/bitbucket/scm/dfdl/daffodil-nifi.git
View the README for build and installation instructions. Detailed documentation about the processor parameters and usage is available from within NiFi by selection the processor "Usage" option.
Example
A Daffodil PCAP NiFi Template is available as an example of the DaffodilParse and DaffodilUnparse NiFi processors. This template expects both the PCAP git repo and the pcap-filter.xsl to be in the /home/dfdl/ directory. This template reads the dns.cap file in the pcap repository, parses it to XML using Daffodil, filters the XML to remove all packets that contain a specified IP address, unparses the filtered XML back to a pcap file, and outputs the result to /tmp/nifi/results.
