Subject: Re: Scan-like Idiom to Capture a Group as a String Instead of an Array?

Thanks for clarifying the operation of scan -- I mistakenly thought I was 
getting a string when I was actually getting an array, so my original 
question wasn't even correct.  Anyway, all of the methods listed below seem 
to work, and the last one seems especially elegant.

Thanks for the advice!
Chris

line = "name: value"

value = line.scan(%r{name: ([[:alnum:]]+)}i)[0][0]
puts "#{value.class}: #{value}"

value = line.scan(%r{name: ([[:alnum:]]+)}i).first.first
puts "#{value.class}: #{value}"

value = line.match(%r{name: ([[:alnum:]]+)}i)[1]
puts "#{value.class}: #{value}"

value = line[%r{name: ([[:alnum:]]+)}i, 1]
puts "#{value.class}: #{value}"
