Set *default* to avoid errors, add attribute *def*, and select lines.
For example,
shell> cat pb.yml
---
- hosts: localhost
gather_facts: false
vars:
lines:
- regexp: '^text1'
line: 'text1 = {{ VAR1|d("undef") }}'
def: '{{ VAR1 is defined }}'
- regexp: '^text2'
line: 'text2 = {{ VAR2|d("undef") }}'
def: '{{ VAR2 is defined }}'
- regexp: '^text3'
line: 'text3 = {{ VAR3|d("undef") }}'
def: '{{ VAR3 is defined }}'
tasks:
- debug:
var: item
loop: "{{ lines|selectattr('def') }}"
gives
shell> ansible-playbook pb.yml -e VAR1=test
PLAY [localhost]
*********************************************************************
TASK [debug]
*********************************************************************
ok: [localhost] => (item={'regexp': '^text1', 'line': 'text1 = test',
'def': True}) => ansible_loop_var: item item:
def: true
line: text1 = test
regexp: ^text1
