3 issues: 1) RETURN_NULL() was used via the macro NODE_GET_OBJ(), but the function returns false on failure and cannot return null according to its stub. 2) The struct layout of the different implementors of libxml only guarantees overlap between the node pointer and the document reference, so accessing the std zend_object may not work. 3) DOC_GET_OBJ() wasn't using ZSTR_VAL(). Closes GH-16307.
