Remove contents of a include_vars file using Ansible

问题

I have a file filedets.yml which has many IP addresses and the file details listed under each IP. Below example shows just 3 entries however, expect this file to have many more entries of IP and file details. cat filedets.yml:

---
10.9.9.111:
  /tmp/test.jar:
    hash: e6df90d38fa86f0e289f73d79cd2cfd2a29954eb

  /tmp/best.jar:
    hash: e6df90d38fa86f0e289f73d79cd2cfd2a29954eb

10.8.8.44:
  /tmp/conf/extra/httpd-ssl.conf:
    hash: 1746f03d57491b27158b0d3a48fca8b5fa85c0c2

  /tmp/conf/httpd.conf:
    hash: 1746f03d57491b27158b0d3a48fca8b5fa85c0c2

10.7.7.37:
  /tmp/conf/extra/httpd-ssl.conf:
    hash: 1746f03d57491b27158b0d3a48fca8b5fa85c0c2
  /tmp/conf/extra/web.xml:
    hash: 1746f03d57491b28753j39983308igfgja8b5fa85


  /tmp/conf/httpd.conf:
    hash: 1746f03d57491b27158b0d3a48fca8b5fa85c0c2

and so on .....

Given an IP address say 10.8.8.44 I wish to remove the IP and all its file details from filedets.yml. Thus the below entry should be removed from the file.

10.8.8.44:
  /tmp/conf/extra/httpd-ssl.conf:
    hash: 1746f03d57491b27158b0d3a48fca8b5fa85c0c2

  /tmp/conf/httpd.conf:
    hash: 1746f03d57491b27158b0d3a48fca8b5fa85c0c2

The below regex helps me search for the text that needs to be deleted.

grep -Pzo '[^#](^10.8.8.44::)(.|\n)*^(?!( |\n))' /app/filedets.yml

I tried to use state: absent attribute of lineinfile and blockinfile modules with the above regex in my ansible-playbook inorder to remove the desired entry from filedets.yml

Here is my playbook:

   - name: "Remove entry from file."
     lineinfile:
       path: "/app/filedets.yml"
       regexp: "[^#](^10.8.8.44:)(.|\n)*^(?!( |\n))"
       state: absent

Unfortunately this does not work and the entries do not get removed from the filedets.yml.

Can you please suggest how can I get this to work ?
