Regex in Javascript; string between last and one before last “/”

Question

How to get "foo19" out of the following string

"C:\Users\test\AppData\Roaming\test2\storage\foo19\text.txt"

lastIndexOf does not help in this case either; I just want "foo19" which happens between two "\\"s the last "\\" and the one before last "\\". Is it possible with regex?

Answer 1

Assuming foo19 is always the 2nd to last entry:

var str = "C:\\Users\\test\\AppData\\Roaming\\test2\\storage\\foo19\\text.txt";
var parts = str.split("\\");
var foo19 = parts[parts.length - 2];

Answer 2

Here is a regex that capture foo19 in a group, so access with $1.

.*\\(\w*)\\\w*.txt
