Sorting ansible output - sed

Question

Below is my ansible task output.
TASK [debug] **************************************************************************************************** **************************************
ok: [server01] => {
"my_updates.stdout_lines": [
"",
"",
"Title : Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.297.486.0)",
"",
"",
""
]
}
ok: [server02] => {
"my_updates.stdout_lines": [
"",
"",
"Title : 2020-08 Cumulative Update for Windows Server 2016 for x64-based Systems",
"",
"",
""
]
}
I only want entries
Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.297.486.0)
2020-08 Cumulative Update for Windows Server 2016 for x64-based Systems
So i tried below method,
- name: Fetch Update List
shell: echo {{ my_updates.stdout_lines }} | tr -s ' ' | sed 's/[][]//g' | sed 's/u,//g' | sed 's/u //g' | sed 's/ u//g' | sed 's/),/)/g'
delegate_to: 127.0.0.1
register: my_sec_result
when: ansible_os_family == "Windows" and my_updates.stdout_lines | length |int > 0
- debug:
var: my_sec_result.stdout_lines
but this wont help, it gives me below output
TASK [debug] ******************************************************************************************************************************************
ok: [server01] => {
"my_sec_result.stdout_lines": [
"Title : Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.297.486.0) "
]
}
ok: [server02] => {
"my_sec_result.stdout_lines": [
"Title : 2020-08 Cumulative Update for Windows Server 2016 for x64-based Systems "
]
}
How to get only these Entries, At present only one entry each found on each server. There can be multiple entries.
Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.297.486.0)
2020-08 Cumulative Update for Windows Server 2016 for x64-based Systems

Answer 1

In your initial list, reject lines which are empty strings then remove the prepending "Title : " with the regexp_replace filter. The following task does it all in one:
- name: Display updates
debug:
msg: "{{ my_updates.stdout_lines | reject('eq', '') | map('regex_replace', 'Title : (.*)', '\\g<1>') | list }}"
Update: As pointed out by #Vladimir, in this case your can replace reject with select for a cleaner template string:
- name: Display updates
debug:
msg: "{{ my_updates.stdout_lines | select() | map('regex_replace', 'Title : (.*)', '\\g<1>') | list }}"
