Glad to have helped. I find that whenever you do something non-trivial with regular expressions, it is a good idea to have someone else look at it, as no two minds work alike, and they can see what you don't.

I see you only updated the regex in one of the playbook tasks in your article. The issue I pointed out apply to all of the tasks, however, and also for "regexp", as well as "insertafter/before" parameters.
