If you want to catch that very specific format you'd do:

  regex = /\[cid:[0-9A-Fa-f]{8}-[0-9A-Fa-f]{4}-[0-9A-Fa-f]{4}-[0-9A-Fa-f]{4}-[0-9A-Fa-f]{12}\]/
  body[0..(body =~ regex).to_i-1]

If you want to loosen it up a little you'd do:

  body[0..(body =~ /\[cid:/).to_i-1]

If you aren't sure there will be content before the [cid declaration then you should pull it out and do this:

  regex = # choose your expression
  test = body =~ regex
  body[0..(test.nil? ? -1 : test - 1)]
