title: How to parsing HTML Content
body: <p>I want do a web crawler news. I want load content from link <em><a href="http://vnexpress.net/tin-tuc/ban-doc-viet/xa-hoi/chay-xe-may-theo-taxi-moi-biet-bi-chem-60-000-dong-2865724.html" rel="nofollow">http://vnexpress.net/tin-tuc/ban-doc-viet/xa-hoi/chay-xe-may-theo-taxi-moi-biet-bi-chem-60-000-dong-2865724.html</a></em> and i want get all content div with class fck_detail <strong>and keep original tag from it</strong> . How to do this ? </p>
  
  <pre><code>    &lt;div class="fck_detail"&gt;
      &lt;p class="Normal" style="text-align:justify;"&gt;Some texts&lt;/p&gt;
      &lt;p class="Normal" style="text-align:justify;"&gt;some texts&lt;/p&gt;
      &lt;p class="Normal" style="text-align:justify;"&gt;Some texts&lt;/p&gt;
      &lt;p class="Normal" style="text-align:justify;"&gt;Some texts&lt;/p&gt;
      &lt;/div&gt;
  </code></pre>
  
  <p>I tried but not success</p>
  
  <pre><code>    $doc = new DOMDocument();
      $doc-&gt;loadHTMLFile("http://example.com/some.html");
      $selector = new DOMXpath($doc);   
      $node = $selector-&gt;query('//div[@class="fck_detail"]')-&gt;item(0);
      echo trim($node-&gt;nodeValue);
  </code></pre>
  
  <p>The above code gives me the plain text stripped from all HTML only. But I want to keep the HTML.    </p>
