title: Trying to extract data using python/scrapy and not able to find the correct xpath
body: <p>I wanted to scrape the website. </p>
  
  <p><a href="https://stackoverflow.com/jobs?med=site-ui&amp;ref=jobs-tab">https://stackoverflow.com/jobs?med=site-ui&amp;ref=jobs-tab</a></p>
  
  <p>I want to extract</p>
  
  <ul>
  <li>Title</li>
  <li>Location</li>
  <li>Company</li>
  </ul>
  
  <p>of the job postings.</p>
  
  <p>I tried few xpath's for the location,company and title and nothing was working. I also tried to write it to a CSV file. All location,company and title comes out blank. I think my xpath is not correct</p>
  
  <pre><code>import scrapy
  
  
  class JobItem(scrapy.Item):
      # Data structure to store the title, company name and location of the job
      title = scrapy.Field()
      company = scrapy.Field()
      location = scrapy.Field()
  
  class stackoverflow(scrapy.Spider):
      name = 'stack_bot'
      start_urls = ['https://stackoverflow.com/jobs?med=site-ui&amp;ref=jobs-tab']
  
      def parse(self, response):
          for a_el in response.xpath('//div[@class="listResults"]'):
              section = JobItem()
              section['title']   = ?
              section['company'] = ?
              section['location'] = ?
              yield section
  </code></pre>
  
  <p>Can anyone help me with the xpath for the title,company and location. Also the <code>xpath('//div[@class="listResults"]')</code> is correct.</p>
