Question

I would like to get from

abc.js
defghi.es6.js
location-map.js
demographics-map.es7.js
demographics-map.tar.bz

demographics-map.tar.ball

the following: markets-map , filename.abc , filename.ab.def , filename.abc , abc , defghi , location-map , demographics-map , demographics-map with Regex. Can you help?

Answer 1

Your problem is specific so you have one way to solve it, it is to solve it case by case here is a regex you can use :

(.*?)(((\.es\d+)?\.js)|(\.tar\.(bz|zip|ball)))

So you can take only the first group here is regex demo :
