You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: cpe.rb
    path of file: ./repos/ruby-nmap/lib/nmap/xml
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require_relative 'cpe/url'

module Nmap
  cl
    
      def each_cpe
        return enum_for(__method__) unless block_given?

        @node.xpath('cpe').each do |cpe|
          yield URL.parse(cpe.inner_text)
        end

        return self
      end
