$xml = new SimpleXMLElement($data);

echo $xml->ns2->api:groups->entry->value->apilisting-entry->value->{get};

There is a typo in your code.

echo $xml->ns2->api:groups->entry->value->apilisting-entry->value->{get};

should be:

echo $xml->ns2->api:groups->entry->value->apilisting->entry->value->{get};

Note the -> after apilisting

And be aware of the :groups namespacing in your xml example.
