php - PHP解析具有多个孩子的xml文件：我只得到第一个

问题描述

我正在使用 foreach 循环解析带有“file_get_contents”的 XML 文件。在 XML 文件中有几个孩子 () 我想列出所有这样的：

<a href="https://rssdomain.com/the-impact-of-brexit">The impact of Brexit</a>
<a href="https://rssdomain.com/new-rules-recording">New Rules on Recording</a>

我得到的 XML 文件：

<rss version="2.0">
<channel>

<link>https://rssdomain.com</link>

</channel>
</rss>

这是我的 PHP 代码：

$source = 'https://rssdomain.com/feed.xml';
    $xmlstr = file_get_contents($source);
    $blogposts = new SimpleXMLElement($source,null,true);

    foreach($blogposts as $item) {
      echo '<h2><a href="'.$item->item->link.'">'.$item->item->title.'</a></h2>';
      // output:  <a href="https://rssdomain.com/the-impact-of-brexit">The impact of Brexit</a>
    }

...我不知道为什么这个 foreach 循环只返回第一项内容，而不是所有内容。我做错了什么？！

解决方案

为自己找到了解决方案：

foreach($blogposts->channel as $channel) {
    foreach($channel->item as $item) {
        echo '<h2><a href="'.$item->link.'">'.$item->title.'</a></h2>';
    }
}
