XMLReader - Class not found

[ShootingStar]

i'm using php5.1 which is supposed to have XMLReader included and enable.

however when i try to use it i get a class not found error

my code is below

class Config 
{

function __construct(){
	$oXMLReader = new XMLReader();

	$oXMLReader->open("../../config/config.xml");

	if ($oXMLReader->isValid())
	{
		print("true");
	}
	else 
	{
		print("false");
	}


}

}

Fatal error: Class 'XMLReader' not found in C:\www\phpsite2\modules\core\config.php on line 7

line 7 being :

$oXMLReader = new XMLReader();

does anyone know why this error is occuring when php comes with xmlreader pre-installed?

So have you checked that it is (it can be disabled, after all)?

It is enabled on my webserver I can see this in the phpinfo()

but I am using Zend Studio and the phpinfo() for the internal debugger doesn't mention XMLReader.

I've tried looking in the webserver php.ini file for reference to xmlreader so that i can copy it to the zend studio php.ini file, but i cannot see xmlreader in my webserver php.ini - even tho the phpinfo() says its enabled?

where is the xmlreader enabled?
