Цикл переполнения стека объектов XML
Это расстраивает меня! Это кажется таким простым, но я не могу пройтись по этому XML на всю жизнь. Я получаю обратно объект SimpleXMLElement по этой ссылке (http://www.nfl.com/liveupdate/scorestrip/ss.xml). Я пытаюсь перейти к массиву g и получить атрибуты [0], [1], [2] и т. Д. Я просто изучаю PHP. Так что любая помощь будет оценена.
Код, который я пробовал:
$nfl = simplexml_load_file('http://www.nfl.com/liveupdate/scorestrip/ss.xml');
foreach ($nfl as $game) {
print '<pre>';
print_r($game);
print '</pre>';
}
Это выводит:

Я пробовал этот foreach, но он ничего не выводил:
foreach ($nfl->g as $game) {
print '<pre>';
print_r($game);
print '</pre>';
}
Решение
$nfl->g не существует, и вам также нужно получить атрибуты, а не содержимое, так как они все пустые. Вы должны иметь успех со следующим. Обратите внимание на правильную глубину в XML $nfl->gms->g, Также обратите внимание на использование attributes() вызов.
$nfl = simplexml_load_file('http://www.nfl.com/liveupdate/scorestrip/ss.xml');
print '<pre>';
foreach ($nfl->gms->g as $game) {
foreach($game->attributes() as $a => $b) {
echo $a,'="',$b,"\"\n";
}
echo "\n------------------------------------------\n";
}
print '</pre>';
