</foo>

How can I access attributes like id or default?

Use the array syntax for attributes and object syntax for child nodes:

$xml->foo['id']  // get `id` attribute on `foo` node

See the Using attributes example here: http://docs.php.net/manual/en/simplexml.examples-basic.php#example-4741

See also the attributes() method.
