$note=<<<XML
<?xml version="1.0" encoding="ISO-8859-1"?>
<book>
    <name>PHP</name>

</book>
XML;

$xml=new SimpleXMLElement($note);
echo $xml->body;
?>

Assume we have the following XML file, "note.xml":

<?xml version="1.0" encoding="ISO-8859-1"?>

<book>//from   jav  a  2  s . c o m

echo $xml->asXML();
?>
