xccdf_results_mapper undefined method `match'

[ccoffin]

Trying to convert some OpenSCAP produced XCCDF results XML into HDF using xccdf_results_mapper on two different systems and have received the following error message in each case.

[number6@localhost Documents]$ sudo docker run -it -v $(pwd):/share mitre/heimdall_tools xccdf_results_mapper -x rhel7scap_2.xml -o hdf_results.json
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
