Thanks. I've got it reading in a file and checking each line against a
regular expression.

How would I go about taking individual sections of a line?
i.e. if the word 'example:' appears on a line then it takes that and a
few characters before or after it (it will be something specific its
just the question is in general here) so for
blah blah blah example: twenty blah blah
it returns me 'example: twenty'

----------------------------------

#!/usr/bin/ruby -w

data = "blah blah blah blah example: twenty blah blah blah blah"

result = data.scan(%r{(example: \w+)}).flatten

puts result

----------------------------------

output:

example: twenty
