Php 如何迭代作为SimpleXMLElement对象的XML值

我将一个XML流解析为一个SimpleXMLElement对象，并尝试迭代可用的记录以用作PHP页面中的值

[listing]的父节点当前存在两次，因为测试XML中有两条记录（清单[0]和清单[1]） 但是我不能让它像PHP手册中的“基本SimpleXML用法”那样工作

    <?php
    $xml = simplexml_load_file('http://feed.postlets.com/Burndog/6458ec1af54f632');

这无法遍历可用值：

    foreach ($xml->listing->title as $title) {
    echo $title;
    }
    ?>

打印文件中的值：

SimpleXMLElement Object

[listing] => Array
    (
        [0] => SimpleXMLElement Object

那么，当图片中有多个元素时，需要通过哪些元素进行循环？

谢谢

正如您在打印输出中看到的，XML对象的“listing”字段是数组，而不是标题。因此，您需要做的是遍历列表并打印出每个列表标题：

foreach ($xml->listing as $listing)
{
    echo $listing->title;
}

要打印图片，请执行以下操作：

foreach ($xml->listing as $listing)
{
    echo "Title: " . $listing->title . "<br>";

    foreach ($listing->photos->children() as $child)
    {
        echo $child . "<br>";
    }
}

foreach（$xml->listing as$listing）
{
回显“标题：”.$listing->Title.“
”；
foreach（$listing->photos->children（）作为$child）
{
echo$child。“
”；
}
}

您的第一个foreach功能完美。。。第二个渲染：photos=>photos=>我将进一步研究它，因为您的值可能只是表示，我需要插入实际字段值。使用alternative编辑，希望有帮助。ccKep，您的foreach产品的结果：标题：3BR/2BA已生产-博蒙特照片数量：0.5标题：2BR/1+1BA已生产-博蒙特照片数量：0.5不知道您现在是否解决了此问题。如果没有，请尝试上面编辑的代码（下面的代码“可选”）并进行检查。结果：标题：3BR/2BA已制造-博蒙特照片1照片2照片3标题：2BR/1+1BA已制造-博蒙特前视图目标已实现！谢谢，这可能会有帮助：

foreach ($xml->listing as $listing)
{
    echo "Title: " . $listing->title . "<br>";

    foreach ($listing->photos->children() as $child)
    {
        echo $child . "<br>";
    }
}
