SIgning XML with PHP xmlseclibs.php

I can't sign XML with XMLSECLIBS.PHP The connections are successful by NuSoap are valid. But the XML to be missing a few nodes.


require_once('lib/nusoap/nusoap.php');
require_once('lib/xml_signature/xmlseclibs.php');

$client = new nusoap_client('http://ift.tt/1C7EYR3', false);
$response = $client->call( 'getSeed' );
$xml = simplexml_load_string($response);
$xml->registerXPathNamespace('SII', 'http://ift.tt/1sS9H3o');
$events = $xml->xpath('//SII:RESP_BODY' );
$semilla = $events[0]->SEMILLA;

$xml_semilla = "<getToken>\n\t<item>\n\t\t<semilla>$semilla</semilla>\n\t</item>\n</getToken>";

$doc =new DOMDocument();
$doc->formatOutput = FALSE; 
$doc->preserveWhiteSpace = TRUE;
$doc->loadXML($xml_semilla);

$objDSig = new XMLSecurityDSig(FALSE);
$objDSig->setCanonicalMethod(XMLSecurityDSig::C14N);
$options['force_uri'] = TRUE;
$options['id_name'] = 'ID';
$options['overwrite'] = FALSE;
$objDSig->addReference($doc, XMLSecurityDSig::SHA1, array('http://ift.tt/A1C4L2'), $options);
$objKey = new XMLSecurityKey(XMLSecurityKey::RSA_SHA1, array('type'=>'private'));

$pfx = file_get_contents(dirname(__FILE__) . "/Enrique.pfx");

$key = array();

openssl_pkcs12_read($pfx, $key, "123456");

$objKey->loadKey($key["pkey"]);
$objDSig->add509Cert($key["cert"],TRUE,FALSE);
$objDSig->sign($objKey, $doc->documentElement); 

$doc->save(dirname(__FILE__) . '\archivo_semilla_firmada.xml');

//====================================================================
//                     SE GENERA TOKEN
//====================================================================
$fsemilla = fopen( 'archivo_semilla_firmada.xml', "r+" );

$fsemilla_firmada = fread( $fsemilla, filesize('archivo_semilla_firmada.xml') );

$client2 = new nusoap_client('http://ift.tt/1zdar78', false);

$respuesta_sii_con_token = $client2->call( 'getToken', array('pszXml' => $fsemilla_firmada) );

echo "<pre>";
    print_r($respuesta_sii_con_token);
echo "<pre>";

file_put_contents( 'token.xml', $respuesta_sii_con_token );

And the result is: archivo_semilla_firmada.xml


<?xml version="1.0"?>

            </ds:X509Data>
        </ds:KeyInfo>
    </ds:Signature>
</getToken>

But is not create nodes in (Example http://ift.tt/1C7EYRd)
