I have come across a problem that I cannot see to solve. I have extracted a line from a web page into a variable. lets say for argument sake this is:

rhyme = “three blind mice Version 6.0”

and I want to be able to first of all locate the version number within this string (6.0) and secondly extract this number into another seperate variable – (I want to specifically extract no more than “6.0”)

I hope I have clarified this enough, if not please ask me anything you need to know and I will get back to you asap.

    First you need to decide what the pattern for a version number should be. One possibility would be \d+(\.\d+)*$ (a number followed by zero or more (dot followed by a number) at the end of the string).

    Then you can use String#[] to get the substring that matches the pattern:

    rhyme[ /\d+(\.\d+)*$/ ] #=> "6.0"
