PHP 使用 PHPSimpleXML 从 XML 获取数据
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 Player1PHP演示 -

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: 3141.29Action: MovePrimary Object Data:ID: 487Name: Player1Country: usSecondary Object Data:ID: 814Name: DogParent: 487
