I'm trying to access the value of the url-authentication key, but it displays the following message: 

Notice: Use of undefined constant autenticacao - assumed 'autenticacao' in
SimpleXMLElement Object
(
[@attributes] => Array
(
[versao] => 1.3.0
[id] => 123
)

[url-autenticacao] => https://qasecommerce.cielo.com.br/web/index.cbmp?id=789b9ef9858bf2aba2751df3f306424a
)
Tentei usar o echo $xml->url-autenticacao mas apresentou a mensagem de erro descrito acima.

How do I get the value of this key?

Elements of SimpleXMLElement obey the PHP variable name conventions, and - is not a permitted character.

In this case, use { and } to encapsulate the name of these elements: 

echo $xml->{'url-autenticacao'};

This form can also be used when you want to use the value of variables: 

$elemento = 'pipoca';
echo $xml->{$elemento};

See more examples on manual PHP online .
