Hi Team, I need some piece of advice how to implement join in OVAL for variables if some of them are empty .
I'm looking at the existing example from master which uses <concat>-<split>. However this code doesn't work as expected for empty variable var_rfg_include_config_regexin <concat> - returned result "no value", while expected would be "%^/etc/rsyslog.conf$": https://github.com/ComplianceAsCode/content/blob/master/linux_os/guide/system/logging/ensure_rsyslog_log_file_configuration/rsyslog_files_groupownership/oval/shared.xml#L43 Note: UniqueFunctionType <https://oval.mitre.org/language/version5.11/ovaldefinition/documentation/oval-definitions-schema.html#UniqueFunctionType> looks more applicable here, but it doesn't work as well with the same reason - returned result is "no value" when one of variables is empty. Can any approach be suggested to avoid getting "no value" and return expected result for sample var_rfg_all_log_files_as_string_regexvariable (with joined values from defined only variables/objects)? Regards, Ilya.
