You need to use the xpath function:

$xml = simplexml_load_string($xml);
foreach ($xml->xpath('//b') as $item) {
    echo $item->id . $item->name . PHP_EOL;
}

or if you want print just name:

$xml = simplexml_load_string($xml);
foreach ($xml->xpath('//name') as $name) {
    echo $name . PHP_EOL;
}
