title: xpath syntax for selecting the text after <strong> tag
body: <pre><code>&lt;div class="article_details"&gt;
  &lt;h1&gt;Product name is&lt;/h1&gt;
  &lt;div class="left"&gt;
  &lt;ul class="article_list"&gt;
  &lt;li&gt;
  &lt;strong&gt;art. nr.:&lt;/strong&gt;
  VS7896
  &lt;/li&gt;
  &lt;li&gt;
  &lt;b&gt;Shipping time&lt;/b&gt;
  : 1-3 Days
  &lt;/li&gt;
  &lt;/ul&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I used <code>//DIV[@class='left']/UL[1]/LI[1]</code> but the result is "<strong>art. nr.: VS7896</strong>".</p>
  
  <p>Please help me with the correct XPath to select just "<strong>VS7896</strong>".</p>
