      XR has “show operational … json” or “… xml” commands. For example:
RP/0/0/CPU0:R5#show operational Interfaces InterfaceBriefTable InterfaceBrief/InterfaceName=GigabitEthernet0/0/0/0 json

I don't know if -XR does this, but on Junos , | display xml or display
json.
Having some structure at least makes the scraping slightly less painful.
Sadly, it's not that easy on XR :(

Warm regards,
