Andrei Andriushin:
@Chandra Mohanty Hi!
Looks like a mistype. Can you share playbook and config file example?
It is also a good practice to use dynamic jinja templates with Ansible

  • name: “Insert new tag RSWindowsBasic after RSWindowsNTLM present in the config file”
    tags: authtaginfile

Chandra Mohanty:
I want to insert a tag <WindiwsBasic/> after <WindowsNTLM/>

Chandra Mohanty:
hi @Andrei Andriushin / @BR

#9

Andrei Andriushin:

- name: "Insert new tag"
  tags: authtaginfile
  ansible.builtin.lineinfile:
   path: 'C:\rsreportserver.config'
   line: '&lt;WindowsBasic/&gt;'
   insertafter: '&lt;WindowsNTLM/&gt;'
  register: authtaginfile
#10

Andrei Andriushin:
Try this one. As insertafter looks for a regular expression I’m not sure this will work. I would strongly recommend template module for this example, because lineinfile can make unpredictable changes another time if file will be changed from outside
