Regex to match url with or without 'folder'

I'm struggling to get the right regex to match the following;

content/foo/B6128/8918/foo+bar+foo

OR

content/foo/B6128/8918/foo+bar+foo/randomstringnumsletters

I'm sure this isn't that complicated and I'm nearly there, just can't get it perfected. Here's what I've tried;

content\/(\w+)\/(\w+)\/(\d+)\/([^\/]+[\w]+)\/?(\w*)$

using this online tester: http://regex101.com/r/sB8rR5/2

It still matches a 5th item with this string content/foo/B6128/8918/foo+bar+foo;

And while technically this pattern does match either OR url structures. I don't want it to match the 5th item when there's no randomstringnumsletters present.

After playing around with it for a bit, I do realise some elements are redundant with what I've tried, but I'm not getting anywhere with it...

Just turn the last capturing group into an optional one, and change \w* to \w+ in the last capturing group inorder to prevent null character to be captured by the 5th group.

content\/(\w+)\/(\w+)\/(\d+)\/([^\/]+[\w]+)\/?(\w+)?$

You can take each part as an array, then take the part that you need...

Looks like your REAL pattern should be:

content\/((?:\w+\/?)+)

DEMO

or am I wrong? This will match the whole string (after content/) and return it all / delimited. You can parse each variable from there.
