With TTP parser, how capture data in a group with two lines starting with the same word

Question

With TTP parser, how can I capture the prefix-limit in the following BGP config from Nokia device? I have two prefix-limit lines in the config, one for ipv4, the other for ipv6; I need to extract both.

                neighbor 192.168.102.41
                    description "blablabla"
                    authentication-key "hashed-key-here" hash2
                    prefix-limit ipv4 600 threshold 80
                    prefix-limit ipv6 601 threshold 81
                    import "policy-1" "policy-2" 
                    export "policy-3" "policy-4" 
                    graceful-restart
                        stale-routes-time 360
                        restart-time 120
                        enable-notification 
                    exit
                    peer-as 65510
                    bfd-enable
                exit

This is the TTP template I came up with,

            <group name="neighbor.{{ neighbor }}">
                neighbor {{ neighbor | _start_ }}
                    family {{ address_family | default("ipv4") }}
                    description {{ description | ORPHRASE | macro("remove_quot_marks") }}
                    authentication-key {{ auth_key | macro("remove_quot_marks") }} hash2
                    prefix-limit {{ family }} {{ prefix_limit }} threshold {{ threshold }}
                    peer-as {{ peer_AS_number }}
                    import {{ import_policy | ORPHRASE | macro("extract_import_export_policy") }}
                    export {{ export_policy | ORPHRASE | macro("extract_import_export_policy") }}
                    bfd-enable {{ bfd_enabled | set("enabled") }}
                exit {{ _end_ }}
            </group>

This only extracts the config for ipv4; the config for ipv6 is ignored. I tried to replace the prefix-limit line in the above template the following two lines,

                    prefix-limit ipv4 {{ ipv4_prefix_limit }} threshold {{ ipv4_threshold }}
                    prefix-limit ipv6 {{ ipv6_prefix_limit }} threshold {{ ipv6_threshold }}

This also only extracts the config for ipv4; the config for ipv6 is totally dismissed.

But if my TTP template has this one line only as shown below, then I can extact the config for both ipv4 and ipv6,

                        prefix-limit {{ family }} {{ prefix_limit }} threshold {{ threshold }}

the following is the parsed data with the above template,

[
{
    "family": "ipv4",
    "prefix_limit": "600",
    "threshold": "80"
},
{
    "family": "ipv6",
    "prefix_limit": "601",
    "threshold": "81"
}
]

How can I get this to work together with other configs, like in my first TTP template?

Thanks, Harry

Answer my own question, the following TTP template worked for the sample config in my question. (My mind must be somewhere else a moment ago)

            <group name="neighbor.{{ neighbor }}">
                neighbor {{ neighbor | _start_ }}
                    family {{ address_family | default("ipv4") }}
                    description {{ description | ORPHRASE | macro("remove_quot_marks") }}
                    authentication-key {{ auth_key | macro("remove_quot_marks") }} hash2

                    <group name="prefix_limit.{{family}}">
                    prefix-limit {{ family }} {{ prefix_limit }} threshold {{ threshold }}
                    </group>
                    
                    peer-as {{ peer_AS_number }}
                    import {{ import_policy | ORPHRASE | macro("extract_import_export_policy") }}
                    export {{ export_policy | ORPHRASE | macro("extract_import_export_policy") }}
                    bfd-enable {{ bfd_enabled | set("enabled") }}
                exit {{ _end_ }}
            </group>
