This might help you on your way:

<CODE>
data = [
  "Oh my dear JabberWock, ", 
  "won't you jubjub",
  "my JubJub?", 
  "juicy-fruit", 
  "fartislab" ]
keywords = ["jabberwock", "jubjub" ]
regexps = keywords.collect{|kw| Regexp.new(kw, Regexp::IGNORECASE ) }

data.each{|line|
  regexps.each{|r|
    if r =~ line then
      puts line
      break
    end
  }
}
</CODE>
