Regex everything after, but not including

Question

I am trying to regex the following string:

https://www.amazon.com/Tapps-Top-Apps-and-Games/dp/B00VU2BZRO/ref=sr_1_3?ie=UTF8&qid=1527813329&sr=8-3&keywords=poop

I want only B00VU2BZRO.

This substring is always going to be a 10 characters, alphanumeric, preceded by dp/.

So far I have the following regex:

[d][p][\/][0-9B][0-9A-Z]{9}

This matches dp/B00VU2BZRO

I want to match only B00VU2BZRO with no dp/

How do I regex this?

Answer 1

Here is one regex option which would produce an exact match of what you want:

(?<=dp\/)(.*)(?=\/)

Demo

Note that this solution makes no assumptions about the length of the path fragment occurring after dp/. If you want to match a certain number of characters, replace (.*) with (.{10}), for example.
