title: PHP DomDocument output without <?xml version="1.0" encoding="UTF-8"?>
body: <p>is there an option with DomDocument to remove the first line:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
  </code></pre>
  
  <p>The class instantiation automatically adds it to the output, but is it possible to get rid of it?</p>
