problem #1)
The return value of "node->attributs()" is not ARRAY; ( 8 line of test.php )
if i put var_dump($attributes); at 8 line in test.php, result of var_dump($attributes) is
starnge.
problem #2)
if i put "$node->parent()" at 7 line in test.php for test, test.php script is die.
sorry for poor english.
