Use xpath y me tira este error:

Warning: SimpleXMLElement::__construct(): Entity: line 1: parser error : Start tag expected, '<' not found in /usr/local/pem/vhosts/109127/webspace/httpdocs/ipn_dineromail.php on line 55 Warning: SimpleXMLElement::__construct(): 497 in /usr/local/pem/vhosts/109127/webspace/httpdocs/ipn_dineromail.php on line 55 Warning: SimpleXMLElement::__construct(): ^ in /usr/local/pem/vhosts/109127/webspace/httpdocs/ipn_dineromail.php on line 55 Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as XML' in /usr/local/pem/vhosts/109127/webspace/httpdocs/ipn_dineromail.php:55 Stack trace: #0 /usr/local/pem/vhosts/109127/webspace/httpdocs/ipn_dineromail.php(55): SimpleXMLElement->__construct('497??

Creo que estoy usando la variable incorrecta el codigo es el siguiente:

$xml = new SimpleXMLElement($content);
$resultado = $xml->xpath('/REPORTE/DETALLE/OPERACIONES/OPERACION/ESTADO');

foreach ($resultado as $valor){
echo $resultado; }

Creo que $content, contiene solo texto, pero como no entiendo lo que se hace con esta variable no lo puedo decifrar..
