SimpleXml class not found

After initiating a new SimpleXml object:

$xml = new SimpleXML($xmlStr);

PHP errors out:

Fatal error: Class 'SimpleXML' not found

PHP info reads:

• Simplexml support enab开发者_JAVA百科led
• Revision $Revision: 1.151.2.22.2.35.2.32 $
• Schema support enabled

What could possibly be going wrong?

try SimpleXMLElement

To parse XML, use:

simplexml_load_string($string);

Or:

simplexml_load_file($filename);

These will each return SimpleXMLElement objects, as noted by others.
