How to write a regular expression for a string?

Question

Regular Expressions

Hello. Can someone help a beginner, I'm weak in regular expressions, I don't know how to get the right part out of the string. The line template is:

ru.site.com/product/название-продукта-латиницей-которое-может-быть-от-20-до-100-символов/идентификатор(число)-от-10-до-12символов.html?куча-get-параметров

We need a regular expression that will pull out only an identifier (number) from such a string and hundreds of similar ones. I suspect that the easiest way here is to take from the 3rd slash, but there is still a difficulty that the length of id is not fixed and can be 10, and 11, and 12 characters.

Answer 1

/\/product\/[Az]{20,100}\/([0-9]{10,12})\./
