How about...

class String
   def re_and_search ( *patterns )
      patterns.flatten!
      patterns.collect! do |x|
         x.type == "Regexp" ? x : Regexp.new(Regexp.escape(x.to_s))
      end
      all_match = true
      for x in patterns
         unless self =~ x
            all_match = false
            break
         end
      end
      all_match
   end
end
