title: Xpath selects just some tr
body: <p>I have an html code like this </p>
  
  <pre><code>&lt;table&gt;
  &lt;tr&gt;
      &lt;th&gt;&lt;a href="example.html" title="exemple_title_th"&gt;&lt;/a&gt;&lt;th&gt;
      &lt;td&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;       
  &lt;tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;a href="example2.html" title="exemple_title_td"&gt;&lt;/a&gt;&lt;td&gt;
      &lt;td&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;       
  &lt;tr&gt;
  &lt;tr&gt;
      &lt;td&gt;&lt;a href="example3.html" title="exemple_title_td"&gt;&lt;/a&gt;&lt;td&gt;
      &lt;td&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;       
  &lt;tr&gt;
  &lt;tr&gt;
      &lt;th&gt;&lt;a href="example4.html" title="exemple_title_th"&gt;&lt;/a&gt;&lt;th&gt;
      &lt;td&gt;&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;       
  &lt;tr&gt;
  </code></pre>
  
  <p>    </p>
  
  <p>And I want just the <strong>tr</strong> that don't have a th tag.
  I tried this xpath:</p>
  
  <pre><code>//a[@title="exemple_title_th"]/following::tr 
  </code></pre>
  
  <p>but it returns all <strong>tr</strong> after the first-one, including the following tr that contain the th tag that I don't want. What's wrong in this code?</p>
