title: getting data between particular tags in html
body: <p>I want get the data between particular tags from html data.</p>
  
  <pre><code>&lt;ul&gt;    
      &lt;li&gt;
          More consistent tension control and approximation with each pass than with traditional sutures.
          &lt;ul&gt;                    
              &lt;li&gt;Unique anchor designs provide multiple points of fixation along the device, allowing tension on the device to be maintained during closure.&lt;sup&gt;&lt;a class="reference_link" href="#22"&gt;[22]&lt;/a&gt;&lt;/sup&gt;&lt;/li&gt;
              &lt;li&gt;Compared to traditional sutures, STRATAFIX™ Devices enable surgeons to easily manage tension and control approximation with each pass.&lt;sup&gt;&lt;a class="reference_link" href="#3"&gt;[3]&lt;/a&gt;&lt;/sup&gt;&lt;/li&gt;
          &lt;/ul&gt;
      &lt;/li&gt;
  &lt;ul&gt;
  </code></pre>
