How to read a return xml containing CDATA in PHP

Question

Hello, I’m not very familiar with this kind of feedback on a Soapclient request (by the way, I’m not very familiar with SOAP). The return has an "example]] element, and when I try to read the file, it prints the whole in a single string.

        $url = "http://localhost:12/mtd1/mtd.asmx?wsdl";

    $clientSoap = new SoapClient($url, array('soap_version'   => SOAP_1_2));


    $params = array('Usuario'=>'user', 'Senha'=>'1234', 'limite'=>$ultima);

    $positions = $clientSoap->BuscaEventos($params);

It returns something like:

<BuscarEventosResponse>
    <BuscarEventos>
         <![CDATA[<TeleEvento> <NumeroSequencia>1010</NumeroSequencia></TeleEvento>]]
    </BuscarEventos>
</BuscarEventosResponse>

When listing the child elements of the Search tag, it returns a single string eliminating the children. Could someone assist me in this "problem"?
