<<< is not portable shell, but this script wants to use /bin/sh.  You
need to either rewrite the script to use /bin/bash, or avoid <<<.  And I
think it's easier to just use portable shell:

invalid=false
case $xml in
 *-invalid.xml) invalid=: ;;
esac

Or even make the case statement check invalid and exit status all at the
same time.  I see you already pushed, so I'll write the followup.
