ruby-on-rails - Nokogiri XML 和循环不起作用

Question

我制作了一个脚本来从 indeed.com API 获取数据。我收到回复，但它首先返回每个公司名称，然后在一个 block 中返回每个职位。

我现在得到的:

ecutive KingswoodSales ExecutiveTrainee Van Sales ProfessionalJunior Broker (Opener) - Hong Kong - flights & accomodationTrainee Sales ExecutiveSales AssociateSales Executive
Mercedes-BenzMercedes-BenzMercedes-BenzSwinton GroupPorscheMercedes-BenzElite Sales RecruitmentImperial TobaccoThreeMercedes-Benz

我尝试添加每个 do 循环，但现在它是空白的，我没有收到错误。

我的脚本:

require 'nokogiri'
require 'open-uri'

xmls = Nokogiri::XML(open('http://api.indeed.com/ads/apisearch?publisher=apikey&q=sales&l=&sort=&radius=40&st=&jt=&start=&limit=&fromage=&filter=&co=uk&v=2')) 

xmls.each do |xml|    
  jobtitle = xml.search('jobtitle').text
  company  = xml.search('company').text

  puts jobtitle
  puts company 
end

我的目标是让我的数据像这样:

Company 1
company name
company jobtitle

Company 2
company name
company jobtitle

Company 3
company name
company jobtitle 
...

这是 XML 响应:

Answer 1

您可以为此使用 css 选择器。

xmls = Nokogiri::XML(open('......')) 

xmls.css('results result').each do |xml|
  jobtitle = xml.css('jobtitle').text
  company = xml.css('company').text
  puts jobtitle
  puts company 
end
