从表标题中获取一个元素

Question

<th "data-next="/?operator=comcast&from=hbo#guide" >
<a href="/hbo/" title="HBO">
  <div>
    <img src="//comcast.com/channel_logo/hbo.png?0">
  </div>
  <span>HBO</span>
</a>
</th>
<th "data-next="/?operator=att&from=fox#guide" >
<a href="/fox/" title="fox">
  <div>
    <img src="//att.com/channel_logo/fox.png?0">
  </div>
  <span>FOX</span>
</a>
</th>

我想得到每个链接，是在data-Next所以我想有：/？运算符

编辑：

整个表格标题如下所示：

<thead class="channelLogos"> 
 <tr>  
  <th "data-next="/?operator=comcast&from=hbo#guide"> <a href="/hbo/" title="HBO"> 
    <div> 
     <img src="//comcast.com/channel_logo/hbo.png?0"> 
    </div> <span>HBO</span> </a> </th>(...) 

当我这样做的时候：

Elements elts = doc.select("thead.channelLogos th")
for(Element elt : elts) {
   System.out.println(elt.absUrl("data-next"));
}//elts stores th elements but doesn't print anything

但是像这样：

Elements elts = doc.select("thead.logaStacji th[data-next]");

elts为空（大小=0）

试试这个：

String html = loadHTML(...);

Document doc = Jsoup.parse(html);

Elements elts = doc.select("th[data-next]");

for(Element elt : elts) {
    // Get absolute url stored in data-next attribute
    System.out.println(elt.absUrl("data-next"));
}
