split string in subelements ansible - loops

Question

I have a list of dicts and I want to loop through the list of dicts, and then have an inner loop that splits a string from each dict and loops through that split string. Is there a way to do this?
I've tried a few things:
- debug:
msg: '{{ "Group: " + item.Group + ", AddMembers: " + item.1 }}'
with_nested:
- '{{ domainGroups.list | selectattr("AddMembers", "ne", "") | list }}'
- '{{ AddMembers.split("|") }}'
- debug:
msg: '{{ "Group: " + item.Group + ", AddMembers: " + item.1 }}'
loop: '{{ domainGroups.list | selectattr("AddMembers", "ne", "" ) | list | subelements(AddMembers.split("|")) }}'
The list of dicts:
{
"AddMembers": "",
"Group": "Group1",
"Delete": "1",
},
{
"AddMembers": "members1|members2",
"Group": "Group2",
"Delete": "",
},
{
"AddMembers": "members1|members2|members3",
"Group": "Group3",
"Delete": "",
},
I hoped that one of the things I've tried would work but usually I get some variation of "AddMembers is not defined" or "unicode thing has no attribute "AddMembers""

Update
Declare the variables
my_groups: "{{ domainGroups|map(attribute='Group')|list }}"
my_member: "{{ domainGroups|map(attribute='AddMembers')|
map('split', '|')|
map('select')|list }}"
groups_members: "{{ dict(my_groups|zip(my_member)) }}"
gives
groups_members:
Group1: []
Group2:
- members1
- members2
Group3:
- members1
- members2
- members3
Iterate with subelements
- debug:
msg: "Group: {{ item.0.key }} AddMember: {{ item.1 }}"
with_subelements:
- "{{ groups_members|dict2items }}"
- value
gives (abridged)
msg: 'Group: Group2 AddMember: members1'
msg: 'Group: Group2 AddMember: members2'
msg: 'Group: Group3 AddMember: members1'
msg: 'Group: Group3 AddMember: members2'
msg: 'Group: Group3 AddMember: members3'
Example of a complete playbook for testing
- hosts: localhost
vars:
domainGroups:
- AddMembers: ''
Delete: '1'
Group: Group1
- AddMembers: members1|members2
Delete: ''
Group: Group2
- AddMembers: members1|members2|members3
Delete: ''
Group: Group3
my_groups: "{{ domainGroups|map(attribute='Group')|list }}"
my_member: "{{ domainGroups|map(attribute='AddMembers')|
map('split', '|')|
map('select')|list }}"
groups_members: "{{ dict(my_groups|zip(my_member)) }}"
tasks:
- debug:
var: groups_members
- debug:
msg: "Group: {{ item.0.key }} AddMember: {{ item.1 }}"
with_subelements:
- "{{ groups_members|dict2items }}"
- value

Let's simplify the dictionaries in the first step. The tasks below
- set_fact:
domainGroups_selected: "{{ domainGroups_selected|default([]) +
[ {'Group': item.Group,
'AddMembers': item.AddMembers.split('|')}] }}"
loop: "{{ domainGroups }}"
when: item.AddMembers|length > 0
- debug:
var: item
loop: "{{ domainGroups_selected }}"
give
"item": {
"AddMembers": [
"members1",
"members2"
],
"Group": "Group2"
}
...
"item": {
"AddMembers": [
"members1",
"members2",
"members3"
],
"Group": "Group3"
}
Then loop the list with subelements. The task below
- debug:
msg: "Group: {{ item.0.Group }} AddMember: {{ item.1 }}"
loop: "{{ domainGroups_selected|subelements('AddMembers')|list }}"
gives
"msg": "Group: Group2 AddMember: members1"
"msg": "Group: Group2 AddMember: members2"
"msg": "Group: Group3 AddMember: members1"
"msg": "Group: Group3 AddMember: members2"
"msg": "Group: Group3 AddMember: members3"
