Question

我有一个XML页面holidays.xml和一个php页面holiday(simplexml).php我试图在php页面的表格中显示XML页面的详细信息但无效，但没有给出错误消息但是没有内容显示，有人能指出我正确的方向吗？

<?php
// load the xml file into a simplexml instance variable
$holiday = simplexml_load_file('holidays.xml');

// draw a table and column headers
echo "<table border=\"1\">";
echo " <th>Title</td>
      <th>Link</td>
      <th>Description</td>
      <th>Published Date</td>
      <th>Guid</th>";

// iterate through the item nodes displaying the contents
foreach ($holiday->item as $holiday) {
    echo "<tr>";
    echo "<td>{$holiday->title}</td>";
    echo "<td>{$holiday->link}</td>";
    echo "<td>{$holiday->description}</td>";
    echo "<td>{$holiday->pubDate}</td>";
    echo "<td>{$holiday->guid}</td>";
    echo "</tr>\n";
}
echo "</table>";
?>

holidays.xml

Answer 1

您忘记了foreach循环中的频道节点。

尝试放

foreach ($holiday->channel->item as $holiday) {
    echo "<tr>";
    echo "<td>{$holiday->title}</td>";
    echo "<td>{$holiday->link}</td>";
    echo "<td>{$holiday->description}</td>";
    echo "<td>{$holiday->pubDate}</td>";
    echo "<td>{$holiday->guid}</td>";
    echo "</tr>\n";
}

Xml无法在表格中显示
