Regex for simplifying Amazon product URLs
+3
−3
Amazon product URLs are often very long, but on experimentation it is revealed that the following pattern is sufficient:
https://www.amazon.com/{dp|gp}/$ID
ID is a 10-char string, which I'm guessing is the ASIN. I want to parse out the long URLs into the minimal form. What exactly is the regex for identifying the ID?

The following expression should capture the {dp|gp}/$ID part:
https://www\.amazon\.com/([gd]p/[A-z0-9]{10})
A quick explanation:
- the
\.are there to match periods only (otherwise it would match any symbol), -
[gd]pmatches eithergpordp, -
[A-z0-9]{10}matches exactly 10 alphanumeric characters - The parentheses around these last two components captures them. This is not really necessary, but the matching algorithm will be able to export only this part of the string as well.
