I want to get the value of the Is_success node under Alipay.
That's what my code says.
$message = $doc->getelementsbytagname ("Alipay")->item (0)->nodevalue;
But it seems to get the wrong value. Ask how we can get this value. Thank you

------Solution--------------------
$message = $doc->getelementsbytagname ("is_success")->item (0)->nodevalue;
