AS1221:AS-TELSTRA is 1 member, plus sub member AS1221:AS-CUSTOMERS. However, it only breaks when running it on the sub-member

Hi,
When AS-PATH set is long, it appears the script adds a comma to the end of the custom name defined when running, formatting for Cisco XR

That , as the end of "as-path-set AS-EQUINIX-AP" should not exist.
Issue doesn't exist if you use Juniper instead of Cisco bgpq4 -S APNIC,ARIN,RIPE,LACNIC,AFRINIC,NTTCOM,RADB -l AS-EQUINIX-AP -Jf 23686 AS-EQUINIX-AP | head policy-options { replace: as-path-group AS-EQUINIX-AP { as-path a0 "^23686(.)(703|1421|1668|1828|1921|3491|3731|4653)$"; as-path a1 "^23686(.)(4739|4785|4983|5779|6404|7233|7280|7566)$"; as-path a2 "^23686(.)(7594|7598|7647|7862|8360|8444|9219|9249)$"; as-path a3 "^23686(.)(9280|9336|9351|9512|9554|9584|9651|9720)$";
