我正在尝试从 xml 文件获取数据，但遇到了麻烦，因为该表的级别比我能找到的示例要多一些。我希望能够迭代<Event>as的每个实例<Information>，并且<Events>仅打开和关闭数据。<Event>根据记录的事件数量重复。表结构的示例是：<?xml version="1.0" encoding="utf-8" standalone="yes"?><Information> <Events> <Event> <Time>3141.29</Time> <PrimaryObject ID="487"> <Name>Player1</Name> <Country>us</Country> </PrimaryObject> <Action>Move</Action> <SecondaryObject ID="814"> <Name>Dog</Name> <Parent>487</Parent> </SecondaryObject> </Event> </Events></Information>PHP代码是：<!DOCTYPE html><html><body><?php$xml=simplexml_load_file("data.xml") or die("Error: Cannot create object");foreach($xml->Event as $events) { $id = $events->PrimaryObject->attributes(); $name = $events->PrimaryObject->Name; ... echo $id['ID'].' '. $name; echo "<br>"; }?></body></html>

您必须使用事件
$xml->Events->Event as $events
例如
$xml=simplexml_load_file("data.xml") or die("Error: Cannot create object");
foreach($xml->Events->Event as $events) {
$id = $events->PrimaryObject->attributes();
$name = $events->PrimaryObject->Name;
echo $id['ID'].' '. $name;
echo "<br>";
}
输出
487 Player1

我不确定您到底在寻找什么数据，但这里有所有内容，使用 xpath，您可以选择：
$events = $xml->xpath('.//Event');
foreach($events as $event) {
$dat = $event->xpath('./PrimaryObject')[0];
$time= $event->xpath('./Time');
$id = $dat->xpath('./@ID');
$name = $dat->xpath('./Name');
$country = $dat->xpath('./Country');
$dat2 = $event->xpath('./SecondaryObject')[0];
$action= $event->xpath('./Action');
$id2 = $dat2->xpath('./@ID');
$name2 = $dat2->xpath('./Name');
$parent = $dat2->xpath('./Parent');
echo 'Time: ' . $time[0];
echo "<br>";
echo 'Action: ' . $action[0];
echo "<br>";
echo "<br>";
echo 'Primary Object Data:';
echo "<br>";
echo 'ID: ' . $id[0];
echo "<br>";
echo 'Name: ' . $name[0];
echo "<br>";
echo 'Country: ' . $country[0];
echo "<br>";
echo "<br>";
echo "<br>";
echo 'Secondary Object Data:';
echo "<br>";
echo 'ID: ' . $id2[0];
echo "<br>";
echo 'Name: ' . $name2[0];
echo "<br>";
echo 'Parent: ' . $parent[0];
echo "<br>";
}
输出：
Time: 3141.29
Action: Move
Primary Object Data:
ID: 487
Name: Player1
Country: us
Secondary Object Data:
ID: 814
Name: Dog
Parent: 487
