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: response.rb
    path of file: ./repos/global_sign/lib/global_sign/dv_approver_list
    
    the code of the file until where you have to start completion: module GlobalSign
  module DVApproverList
    class Response < GlobalSign::Response
      module XPath
  
    
      def approvers_list
        @approvers ||= @xml.xpath(XPath::SEARCH_ORDER_DETAIL).map do |approver|
          {
            type: approver.xpath('ApproverType').text,
            email: approver.xpath('ApproverEmail').text
          }
        end
      end
