这是我第一次在这里提问，我也是PHP和简单XML的新手，但我决心学习这个。我已经搜索了之前提出的所有相关问题，但在将其应用于我的情况时遇到了困难，尽管它看起来很相似。真令人沮丧:(。

我正在尝试从 Amazon Cloudsearch 以 XML 格式读取 API 响应。

这是原始的 XML 响应：

<results xmlns="http://cloudsearch.amazonaws.com/2011-02-01/results">
<rank>-text_relevance</rank>
<match-expr>(label '"mango"')</match-expr>
<hits found="99" start="0">
<hit id="mango1to100_csv_31">

我使用 SimpleXML 开始：

我正在尝试读取并显示基于结果中提供的 URL 显示的每个项目的图像。我知道我应该在这里使用“foreach”循环，但我似乎无法做到这一点，所以这是我完成它的漫长道路：

<?php
$feed_url = 'http://www.myapicallexample.com';
$feed = simplexml_load_file($feed_url);

echo "<ul>";
echo "<li><img src='", $feed->hits[0]->hit[1]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[2]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[3]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[4]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[5]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[6]->d,"'></li>";
echo "<li><img src='", $feed->hits[0]->hit[7]->d,"'></li>";
echo "</ul>";
?>

从查看其他问题的答案，我尝试了各种 foreach 语句的组合，但没有任何效果。我准备把我的电脑扔出窗外。提前致谢！

附录：这是我之前的许多愚蠢尝试之一的一个例子：）

<?php
$feed_url = 'http://www.myapicallexample.com';
$xml = simplexml_load_file($feed_url);

$imageurl = $xml->hits[0]->hit[1]->d;

foreach($imageurl as $a)
{
  echo $a;
}



?>

$feed_url = 'http://www.myapicallexample.com';
$xml = simplexml_load_file($feed_url);

foreach($xml->hits->hit as $hit){
    echo "url:".$hit->d;
}
