Using variable substitution with replace module and regex

Hi,

I have two register variable in a play and want to replace one with another in a play.

The way your are doing it seems ok, except you are formating it wrong

either use this form:

- name: Editing the file
   replace: dest=/some/path regexp=^"{{ result.stdout }}."
replace="{{ result2.stdout }}." backup=yes

or this one:

- name: Editing the file
   replace:
      dest: /some/path
      regexp: ^"{{ result.stdout }}."
      replace: "{{ result2.stdout }}."
      backup: yes
