java - 如何使用 Jsoup 选择元素

Question

我有一个表，我想在其中迭代根 tbody 中的行 (tr)，而不是子级中的行

我尝试了这个但没有成功:

Elements tableRows = table.select("tr");

这个 get tr 也在它的 child 中，所以我有重复的

Elements tableRows = table.select("tbody > td:first-child");

这也不起作用

这是我的 table :

<table border="0" cellspacing="0" cellpadding="2" width="100%" align="center">
 <tbody>
  <tr>
   <td class="head">Rank</td>
   <td class="Head">&nbsp;</td>
   <td class="Lhead">Club</td>
   <td class="head">Nation</td>
   <td class="head">Rank points</td>
   <td class="head">Five best results (by points)</td>
  </tr>
  <tr>
   <td class="playerB">60. (1.)</td>
   <td class="Lplayer"><a href="player.aspx?id=260161">Imrich Blasko</a></td>
   <td class="Lplayer"><a href="club.aspx?id=260008">THC Blue Dragon Kosice</a></td>
   <td class="player"><img src="flags/SVK.gif" alt="SVK" /></td>
   <td class="playerB">3&nbsp;398</td>
   <td class="Lplayer">
    <table border="0" width="100%" cellspacing="0" cellpadding="0">

      <tr>
       <td class="Lplayer"><a href="tournament.aspx?id=14379">World Championships 2013</a></td>
