使用RegEx匹配URL中的ID

Question

I am looking to find a random alpha-numeric ID from a URL returned in some JSON. Using the example:

"responseURL" : "http://sutureself.com/userid/123abc"

... I want to just match on the 123abc . So far I have:

http://sutureself.com/userid/([a-z0-9]+)

... but this matches the whole URL. What do I need to add to only match this ID? Note, the length of the ID can differ.

Answer 1

How about this:

[^/]+(?="})

Looks like you need to set the template to "$1". See comments in this related post.
