Regex to match URL end-of-line or “/” character

regex

I have a URL, and I'm trying to match it to a regular expression to pull out some groups. The problem I'm having is that the URL can either end or continue with a "/" and more URL text. I'd like to match URLs like this:

But not match something like this:

So, I thought my best bet was something like this:

/(.+)/(\d{4}-\d{2}-\d{2})-(\d+)[/$]

where the character class at the end contained either the "/" or the end-of-line. The character class doesn't seem to be happy with the "$" in there though. How can I best discriminate between these URLs while still pulling back the correct groups?

To match either / or end of content, use (/|\z)

This only applies if you are not using multi-line matching (i.e. you're matching a single URL, not a newline-delimited list of URLs).


To put that with an updated version of what you had:

/(\S+?)/(\d{4}-\d{2}-\d{2})-(\d+)(/|\z)

Note that I've changed the start to be a non-greedy match for non-whitespace ( \S+? ) rather than matching anything and everything ( .* )
