<"sample.xml");
  echo htmlspecialchars($xml->asXML());
"htmlcode">

<library>
  <book>
   <title>A</title>
   <author gender="female">B</author>
   <description>C</description>
  </book>
  <book>
   <title>C</title>
   <author gender="male">D</author>
   <description>E</description>
  </book>
  <book>
   <title>F</title>
   <author gender="male">G</author>
   <description>H</description>
  </book>
</library>
