I want to use simplexml in my controller php, but I get an error (Node no longer exists).

I suspect ->children() is calling the silverstripe function rather than the simplexml children() function.

Is there any way around this?

class TypeTester_Controller extends Page_Controller {

function MyFunction() {

$xml = simplexml_load_file('myXML.xml');

foreach($xml->library->children() as $child) {
...
}
}
}

Thanks
