I need a regular expression to parse out the companyid and branchid in a url. The issue is that the branchid may occur at the end of the string or it may occur in the middle of the string. it will always follow /branches. Here are 2 examples:

http://localhost:8080/customer-api/customers/1128952/branches/83370
http://localhost:8080/customer-api/customers/1128952/branches/83370/validate

where 1128952 is the customerid and 83370 is the branchid

Now I know that

^.customers/(.?)/branches/(.*?)$

parses out the customerid and branchid for the first example and

^.customers/(.?)/branches/(.?)/.$

parses out the customerid and branchid for the second example

My problem is I want one regex to parse out the branchid that covers both cases. Can anyone help?
