try something like below.

replace parent with subscription-id

replace avp1 with subscription-id-type, avp1 value would be either 0 or 1 (set to match what you are looking for)

replace avp2 with subscription-id-data

vendor-id is optional, you can remove them or set to 0

# <parentAvpName>
set count [DIAMETER::avp count <parentAvpCode> vendor-id <parentAvpVendorId>]
set index 0
set myavp ""
while { $index < $count } {
    set parent [DIAMETER::avp data get <parentAvpCode> grouped vendor-id <parentAvpVendorId> index $index]
    # <avp1Name>
    set child [DIAMETER::avp data get <avp1Code> <avp1Format> vendor-id <avp1VendorId> source $parent]
    if { $child == "<avp1ValueId>" } {
        # <avp0Name>
        set myavp [DIAMETER::avp data get <avp0Code> <avp0Format> vendor-id <avp0VendorId> source $parent]
        break
    }
    incr index
}

note that you can generate this from diameter wizard (or diameter iAppsLX)

Thanks P'Nat, it works! The index is exactly the solution.

Here is my code from your suggestion.

###P'NAT HINT####

set count [DIAMETER::avp count 443 ]
set index 0
set myavp ""
while { $index < $count } {
set parent [DIAMETER::avp data get 443 grouped index $index]
# <avp1Name>
log local0. "Inx: $index"
log local0. "Codes Parent: [DIAMETER::avp codes source $parent ]"
set child [DIAMETER::avp data get 450 integer32 source $parent]
if { $child == "1" } {
# <avp0Name>
set myavp [DIAMETER::avp data get 444 string source $parent]
log local0. "imsi: $myavp"
break
}
incr index
}

Then i got what i want already, Thanks alot for your kindly help krab.
