title: Extracting attribute with simplexml_load_string
body: <p>I'm trying to extract the href attribute of link as a string.</p>
  
  <pre><code>&lt;a href="http://example.com" target="_blank" class="someclass"&gt;Read More&lt;/a&gt;
  </code></pre>
  
  <p>I'm using the following to read the extract the attribute:</p>
  
  <pre><code>$link = simplexml_load_string($ad['meta_value']);
  $order['logo'] = $logo['href']-&gt;asXML();
  </code></pre>
  
  <p>Instead of getting <code>http://example.com</code> I'm getting <code>href="http://example.com"</code>. Beside using str_replace() is there a way to extract the attribute as a string?</p>
