Datalife Engine Noindex Hack

After 5 years I am back on using Datalife Engine CMS.
And one of the problem I faced when trying to rank well for SEO was no index for tags, xfields or other pages I didn't want to.
In wordpress it is simple, installing plugins making it easy to solve this problem but not for DLE, after searching found this great hack which gets the work done.
