这令我很沮丧！它看起来很简单，但我不能在我的生活中循环使用这个XML。我从这个链接（http://www.nfl.com/liveupdate/scorestrip/ss.xml）获得了一个SimpleXMLElement对象。我正在尝试向下钻取到g数组并获得[0]，[1]，[2]等的属性。我只是在学习PHP。所以任何帮助都会受到赞赏。
我试过的代码：
$nfl = simplexml_load_file('http://www.nfl.com/liveupdate/scorestrip/ss.xml');
foreach ($nfl as $game) {
print '<pre>';
print_r($game);
print '</pre>';
}
输出：

我尝试了这个foreach，但它没有输出任何内容：
foreach ($nfl->g as $game) {
print '<pre>';
print_r($game);
print '</pre>';
}
答案 0 :(得分：1)
$nfl->g不存在，您还需要获取属性而不是内容，因为它们都是空白的。您应该获得以下成功。请注意XML $nfl->gms->g中的正确深度。另请注意使用attributes()电话。
$nfl = simplexml_load_file('http://www.nfl.com/liveupdate/scorestrip/ss.xml');
print '<pre>';
foreach ($nfl->gms->g as $game) {
foreach($game->attributes() as $a => $b) {
echo $a,'="',$b,"\"\n";
}
echo "\n------------------------------------------\n";
}
print '</pre>';
