I found lot of solutions for this problem, but my code won't work!
XML INFO:
<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
<S:Body>
<ns2:resultado xmlns:ns2="http://webservice.consulta.spcjava.spcbrasil.org/" data="2014-06-03T11:37:32.001-03:00" restricao="false">
<protocolo digito="2" numero="1204248496" />
.... other XML info
MY CODE:
$s = '<?xml version="1.0" encoding="UTF-8"?><S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Body><ns2:resultado xmlns:ns2="http://webservice.consulta.spcjava.spcbrasil.org/" data="2014-06-03T11:37:32.001-03:00" restricao="false"><protocolo digito="2" numero="1204248496" /> ...
$xml = simplexml_load_string($s);
$x2 = $xml->children('http://schemas.xmlsoap.org/soap/envelope/')->Body->children('http://webservice.consulta.spcjava.spcbrasil.org/')->resultado->protocolo->digito;
print_r($x2);
var_dump(count($x2));
Returns null and 0 for the object count.
I've been following this tutorial: http://amigotechnotes.wordpress.com/2013/11/16/parse-xml-with-namespace-by-simplexml-in-php/
I don't get where my example differs from his example. :/
Can anyone help me with this issue, please?

Finally made it work using another syntax.
$xml = simplexml_load_string($resultadoDocumento[0]["cdo_xml"]);
$resultadoSPC = $xml->children('S', TRUE)->Body->children('ns2', TRUE)->children();
accessing nodes by:
<?php foreach ($resultadoSPC->consumidor->children()->{"consumidor-pessoa-fisica"} as $consumidorElement) : ?>
<?php echo $consumidorElement->attributes()->{"nome"}; ?>
