JSOUP解析两个表

Question

我已经解析了第一个表，但我不知道如何解析第二个表。

<div class="catItemHeader" style="position: absolute;"> 
    <h3 class="catItemTitle" style="color: #982C37;font-size: 30px;font-weight: 600;">Arrivi</h3> 

    <div style="color: #982C37; margin-left: 104px;margin-top: -20px;font-weight: bold;"> 
     <label>Ultimo aggiornamento:</label> 17/04/2014 10:12 </div> 
    <table class="tabella-voli">

      <th>Stimato</th> 
      <th>Stato</th> 
     </thead> 
     <tbody> 
         <tr style="background-color: rgba(253, 253, 253, 0.8);">

第一个表与解析：

org.jsoup.nodes.Document doc = Jsoup.connect("http://site.eu").timeout(7*1000).get(); 

org.jsoup.nodes.Element tabella = doc.getElementsByClass("tabella-voli").first(); 
Iterator<org.jsoup.nodes.Element> iterator = tabella.select("td").iterator(); 

while(iterator.hasNext()){ 

你能不能帮我分析只有第二个表？我只需要td元素。

Answer 1

您可以直接invoque“first（）”来实例化一个Elements类。 然后，你将能够解析您希望与“获取（INT）”的方法表：

Elements tables = currentServerPage.getElementsByClass("tabella-voli"); 
Element secondTable = tables.get(1); 
Elements tdElements = currentServerPage.getElementsByTag("td"); 

然后你会得到元素的列表，包含所有“TD”第二个表。
