Replace multiple lines in a file at different locations

[Suresh Grandhi]

I am looking to replace or delete redundant lines in a file at different line numbers. 

For example, a file has the following content

<value1> <text1>

<value2> <text2>

<value3> <text1>

In this case, I want to remove <value1> <text1>  and replace <value3> <text1> with <valuex> <text1>.

Is there a possibility to do this in Ansible?

Maybe http://docs.ansible.com/ansible/lineinfile_module.html will help?

[wani@linux tmp ]$ cat /tmp/a

<value1> <text1>

<value2> <text2>

<value3> <text1>

[wani@linux tmp ]$ cat a.yaml 

- hosts: localhost

  tasks:

    - lineinfile:

        path: /tmp/a

        regexp: "^<value1> <text1>"

        state: absent

    - lineinfile:

        path: /tmp/a

        regexp: "^<value3> <text1>"

        line: "<valuex> <text1>"

[wani@linux tmp ]$ ansible-playbook a.yaml 

 [WARNING]: Host file not found: /etc/ansible/hosts
