使用Jsoup提取特定的html表格內容

Question

我想從響應式HTML表格中提取特定內容，我正在使用Jsoup。

這裏是我的表的結構：

<table id="main_widget_table" class="table table-striped table-hover table-condensed table-bordered"> 
       <tbody> 
       <!-- ngRepeat: object in currentView --><tr ng-repeat="object in currentView" class="ng-scope"> 
        <td> 
         <a id="main_widget_table_object_name_action" href="#//object/" target="_blank"> 
          <b class="ng-binding">TASK_BACKUP</b> 
         </a> 

         <p style="font-size:11px"> 
          <span class="text-success" ng-show="object.label"><em class="ng-binding"> task backup</em></span>

      </table> 

我只有一個提取大膽的標記之間的值，例如第一個TD值是TASK_TOTO。

這裏是我的Java代碼：

ublic class HtmlParser { 

public class HtmlParser { 

public static void main(String[] args) throws Exception { 
    Document doc = Jsoup.connect("http://frstmwarwebsrv2.orsyptst.com:9000/ui/#/en/search?searchString=TSK&filterchecks=nameSWF").get(); 
    for (Element table : doc.select("#search_results_table")) { 
     for (Element row : table.select("tr")) { 
      Elements tds = row.select("td"); 
      System.out.println(tds.get(0).text()); 
     } 
    } 
} 

} 

我是一個新手，JSOUP和我的代碼不diplay東西爲止。我正在使用表ID來查找表。

感謝 您的幫助

FYI：採用了棱角分明JS所以Jsoup不提取表數據的最佳方式產生我的表。

當使用此代碼來代替：

List<WebElement> resultsDiv = driver.findElements(By.xpath("id('search_results_table')")); 
     for (int i=0; i<resultsDiv.size(); i++) { 
     System.out.println(resultsDiv.get(i).getText()); 
     System.out.println (resultsDiv.size()); 

我還沒有得到顯示的內容和大小設置爲1！我不確定我做錯了什麼！

Answer 1

那麼，基於HTML片段您提供，該表的id是main_widget_table，不search_results_table。 （在你的代碼的網址不再訪問，所以我不能告訴，如果有該網頁上其他一些search_results_table。）

您可以

for (Element e : doc.select("#main_widget_table b")) 
    System.out.println(e.text()); 

打印所有 b標籤的文本在該表
