body: <p>I would like to select only the p tag without any attributes from the following html code.</p>
  
  <pre><code>&lt;div id="review"&gt;
      &lt;div class="partial_review"&gt;
          &lt;div class="1"&gt;.....&lt;/div&gt;
          &lt;div class="2"&gt;
              &lt;div class='inner_Bubble'&gt;
                  &lt;div class="entry"&gt;
                      &lt;p class="partial_entry&gt;it was a good...&lt;/p&gt;
                  &lt;/div&gt;
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="full_review"&gt;
          &lt;div class="1"&gt;.....&lt;/div&gt;
          &lt;div class="2"&gt;
              &lt;div class='inner_Bubble'&gt;
                  &lt;div class="entry"&gt;
                      &lt;p&gt;it was a good trip.&lt;/p&gt;
                  &lt;/div&gt;
              &lt;/div&gt;
          &lt;/div&gt;  
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I have tried <code>//div[@class='entry']/p[not class = 'partial_entry']/text()</code>. But, its not working.</p>
