Regex to get numbers between the second and third "/"

If it's always product, you can do:

/produto/(\d+)/

(regexplained)

If the prefix changes depending on the case use:

/(\w+)/(\d+)/

(regexplained)

Note that I also captured the prefix in this case.

Depending on the language it may be necessary to add leaks to the bars. Change% with% by% with%.

If you want to remove any text, simply use the following expression

"[^0-9]" ou "[^\d]" 

If it is / product / 976935 / it will return 976935 , but if it is / product / 976935/1 it will return tbm number 1 and would be 9769351

In Java I think it would look something like this:

 var soNumero = soNumero.replaceAll("[^0-9]",""); 

or

 var soNumero = soNumero.replaceAll("[^\d]","");
