Get the number between specified strings

Ok. Given the example of:

http://example.com/news/3226-some-post-title.html

I'm trying to get the 3226. This regexp: http://interaktywnie.com/newsy/(.*).html doesn't seem to work. Please help.

Thanks.

You can just use:

   /\/(\d+)-(.*)\.html$/

This will grab the digits (\d) after the '/' and put the digits into the first variable once it finds them.

A great place to test regular expression is http://rubular.com/.

"http://example.com/news/3226-some-post-title.html".split("/").last.to_i

Try this pattern:

/http:\/\/example\.com\/news\/(\d+)-.+\.html/

So:

match = /http:\/\/example\.com\/news\/(\d+)-.+\.html/.match("http://example.com/news/3226-some-post-title.html")
puts match[1]

You want this:

/http:\/\/example.com\/news\/(\d+)-.+\.html/

\d is any digit. Also, the following site is very useful for regular expressions in ruby:
