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: rss_generator.rb
    path of file: ./repos/wpscan/app/finders/wp_version
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module WPScan
  module Finders
    module WpVersion
      # RSS Generator Version Finder
      class RSSGenerator < CMSScanner::Finders::Finder
        include Finder::WpVersion::SmartURLChecker

        def process_urls(urls, _opts = {})
          found = Findings.new

  
    
        def process_urls(urls, _opts = {})
          found = Findings.new

          urls.each do |url|
            res = Browser.get_and_follow_location(url)

            res.html.xpath('//comment()[contains(., "wordpress")] | //generator').each do |node|
              node_text = node.text.to_s.strip

              next unless node_text =~ %r{\Ahttps?://wordpress\.(?:[a-z]+)/\?v=(.*)\z}i ||
                          node_text =~ %r{\Agenerator="wordpress/([^"]+)"\z}i

              found << create_version(
                Regexp.last_match[1],
                found_by: found_by,
                entries: ["#{res.effective_url}, #{node.to_s.strip}"]
              )
            end
          end

          found
