XML simpleDOM sortedXPath -如何选择和显示父属性？

Question

xml文件：

<?xml version='1.0' encoding='utf-8'?>

<MyName>

<EventGroup Name="Japan Shows" ID="341">
  <Event Name="Sapporo" ID="40163" StartTime="07/07/12 06:00:00" />
  <Event Name="Consadole" ID="5106" StartTime="07/07/12 07:30:00" />
  <Event Name="Albirex" ID="4063" StartTime="07/07/12 05:20:00" />
  <Event Name="Niigata" ID="1144" StartTime="07/07/12 09:00:00" />
</EventGroup>

<EventGroup Name="USA Shows" ID="342">
  <Event Name="Phoenix" ID="40162" StartTime="07/06/12 09:00:00" />
  <Event Name="California" ID="5105" StartTime="07/08/12 08:30:00" />
  <Event Name="Seattle" ID="4062" StartTime="07/08/12 02:20:00" />
  <Event Name="Chicago" ID="1143" StartTime="07/08/12 04:00:00" />
</EventGroup>

</MyName>

代码：

<?php
include 'SimpleDOM.php';
$xml = simpledom_load_file($cache_file);
$count = 0;
$max = 50;

foreach ($xml->sortedXPath("EventGroup/Event", "@StartTime", SORT_ASC) as $EventGroup => $item) {

$time = date("d/m - H:i", strtotime($item['StartTime']));
$event_name = $item['Name'];

    if ($count < $max) {
        echo "$time";
        echo "$event_name";
    }
    $count++;
}
?>

结果：

07/06 - 09:00 Phoenix
07/07 - 06:00 Sapporo
07/07 - 07:30 Consadole
07/08 - 04:00 Chicago

etc...which都正确。

但是如何显示合适的EventGroup名称呢？如何选择和显示每个事件结果的parent name属性？我想要的结果应该是这样的：

USA Shows   07/06 - 09:00 Phoenix
Japan Shows 07/07 - 06:00 Sapporo
Japan Shows 07/07 - 07:30 Consadole
USA Shows   07/08 - 04:00 Chicago

等等。

提前感谢您的帮助！

您可以使用parentNode()获取节点的父节点。然后您可以正常获取属性值：

$parent = $item->parentNode();
echo $parent['Name'];
