Regex start searching from the end of the string (reverse)

Question

I have strings that have blocks enclosed in underscores in them. Example:

*Text* _word_ it is something we read every day. _Words in texts_ can be really exp         


        

Answer 1

Have a try with:

((?:_[^_\r\n]*){2})$

It matches an underscore followed by any number of any character that is not underscore or line break, all that occurs twice before the end of lien.
