title: get list items inside div tag using xpath
body: <p>I have a html like this</p>
  
  <pre><code>&lt;div id="all-stories" class="book"&gt; 
  &lt;ul&gt;
  
  &lt;li title="Book1"  &gt;&lt;a href="book1_url"&gt;Book1&lt;/a&gt;&lt;/li&gt;
  
  &lt;li title="Book2"  &gt;&lt;a href="book2_url"&gt;Book2&lt;/a&gt;&lt;/li&gt;
  &lt;/ul&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p>I want to get the books and their respective url using xpath, but it seems my approach is not working. for simplicity  i tried to extract all the elements under "li " tags as follows</p>
  
  <pre><code>lis = tree.xpath('//div[@id="all-stories"]/div/text()')
  </code></pre>
