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/.

  Chas. Owens : you need to escape that last .

  vrish88 : ah thanks. good eye.

• 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:

  http://www.rubular.com

• 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]
  

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