Question

首先我是一个PHP菜鸟，以为我有简单的xml，但显然不是：）

我只是试图解析一个新闻源并将其回显，但我什么都没得到，而且没有任何错误消息让它变得更难。我可能犯了一个愚蠢的错误......

继承了我写的代码：

<?php

$rss = simplexml_load_file('http://feeds.bbci.co.uk/news/world/rss.xml');

foreach($rss->channel->item as $item) {

    $title = $item['title'];

    echo $title;
    echo '<br /><hr />';
}

?>

下面是xml布局的一个例子：

<rss xmlns:media="http://search.yahoo.com/mrss/" xmlns:atom="http://www.w3.org/2005/Atom" version="2.0">  
  <channel> 
    <title>BBC News - World</title>  
    <link>http://www.bbc.co.uk/go/rss/int/news/-/news/world/</link>  
    <description>The latest stories from the World section of the BBC News web site.</description>

    </item>
  </channel> 
</rss>

任何人都可以看到我的代码有任何明显的错误吗？香港专业教育学院之前使用它并且工作正常：（

谢谢你的时间，

试试这个：

foreach($rss->channel->item as $item) {

    $title = (string)$item->title[0];

    echo $title;

}

简单的xml解析
