Generally you use method Integer() to convert String into an int:

irb(main):001:0> s = "123"
=> "123"
irb(main):002:0> n = Integer(s)
=> 123
irb(main):003:0> n.class
=> Fixnum

In your case you can do this:

irb(main):004:0> s = '<Loading DOM finished: 41 ms>'
=> "<Loading DOM finished: 41 ms>"
irb(main):005:0> n = s[/<Loading DOM finished: (\d+) ms/, 1]
=> "41"
irb(main):006:0> n = Integer(n)
=> 41

Cheers
