Group attribute name used to uniquely identify group and its results within results structure. This attribute is a dot separated string, there is every dot represents a next level in hierarchy. This string is split into path items using dot character and converted into nested hierarchy of dictionaries and/or lists.
Consider a group with this name attribute value:
<group name="interfaces.vlan.L3.vrf-enabled"> interface {{ interface }} description {{ description }} ip address {{ ip }}/{{ mask }} vrf {{ vrf }} </group>
If below data parsed with that template:
interface Vlan777 description Management ip address 192.168.0.1/24 vrf MGMT
This result will be produced:
[ { "interfaces": { "SVIs": { "L3": { "vrf-enabled": { "description": "Management", "interface": "Vlan777", "ip": "192.168.0.1", "mask": "24", "vrf": "MGMT" } } } } } ]
Name attribute allows to from arbitrary (from practical perspective) depth structure in deterministic fashion, enabling further programmatic consumption of produced results.
