Regex for extracting each word between hyphens

Question

I am learning regex and trying to write a pattern that exactly matches each of the strings without'-' so that I can iterate for each of the groups and print the respective strings.

I have a string that looks like "Abcd001-wd2s-vwe1-20180e3103.txt"

I was able to write a regex for extracting Abcd001, wd2s and .txt from above text as shown below

(\A[^-]+)=> Abcd001
(-[^-]+-)=> wd2s
(\..*)=>.txt

However, I was unable to come up with the correct pattern for extracting the exact strings vwe1 and 20180e3103

It will be really helpful if you can guide me on this or if there is a better approach to achieve this?

Please note: [^-.]+ may give me all the words separately but I am looking for an option where I have a group defined for each of these strings so that its one to one mapping.

Thanks!

Answer 1

To get vwe1 or 20180e3103 from the example data, you might use a quantifier {2} or {3} to repeat matching one or more word charcters followed by a hyphen (?:\w+-){2}.

Then you could capture in a group ([^-.]+) matching not a hyphen or a dot.

(?:\w+-){2}([^-.]+)
