  <th class="zwyx">职位月薪</th>
  <th class="gzdd">工作地点</th>
  <th class="gxsj">发布日期</th>
  </tr>
  </tbody>

The following uses jsoup to parse the html to obtain recruitment information:

 public static List<HtmlFeed> parse(String html) {
   Document doc = Jsoup.parse(html);
   Elements elements = doc.getElementsByClass("newlist").select("tr");  
   List<HtmlFeed> list=new ArrayList<HtmlFeed>();

  for (Element ele : elements) {
   if (!ele.select("td").toString().equals("")) {
    String job_url = ele.getElementsByClass("zwmc").select("a").attr("href");
    String job = ele.getElementsByClass("zwmc").text();
    String company = ele.getElementsByClass("gsmc").text();
    String addr = ele.getElementsByClass("gzdd").text();
    String date = ele.getElementsByClass("gxsj").text();

     HtmlFeed feed = new HtmlFeed();
 if (!job_url.toString().equals("")&&!job.toString().equals ("")&&!addr.toString().equals("")&&!company.toString().equals("")&&!date.toString().equals("")) {
  feed.setJob_url(job_url.toString());
  feed.setJob(job.toString());
  feed.setAddr(addr.toString());
  feed.setCompany(company.toString());
  feed.setDate(date.toString());

   list.add(feed);
     }
  }

  }
  return list;
 }
