title: PHP - remove divs and content inside
body: <p><strong>HTML:</strong></p>
  
  <pre><code>&lt;!--a lot of HTML before--&gt;
  &lt;div class="quoteheader"&gt;
    &lt;div class="topslice_quote"&gt;&lt;a href="htsomelink"&gt;Some text&lt;/a&gt;&lt;/div&gt;
  &lt;/div&gt;
  &lt;blockquote class="bbc_standard_quote"&gt;Some text&lt;br /&gt;
  &lt;/blockquote&gt;
  &lt;div class="quotefooter"&gt;
    &lt;div class="botslice_quote"&gt;&lt;/div&gt;
  &lt;/div&gt;
  &lt;br /&gt;
  &lt;!--a lot of HTML after--&gt;
  </code></pre>
  
  <p><strong>I NEED TO:</strong> remove everything between div.quoteheader and first <code>&lt;br/&gt;</code> after, so result should looks like:</p>
  
  <pre><code>&lt;!--a lot of HTML before--&gt;
  &lt;!--a lot of HTML after--&gt;
  </code></pre>
  
  <p><strong>I TRIED:</strong></p>
  
  <pre><code>$message = preg_replace('/&lt;div\sclass=\"quoteheader\"&gt;[^&lt;]+&lt;\/div&gt;/i', '', $string)
  </code></pre>
