Question

好吧，我真的不明白这个概念，但我不想使用小部件来远离他们的广告。

因此，我试图通过客户广播电台网站为福克斯新闻制作10个全国性的结果。我只想要一个链接，所以我需要从Feed中获取标题和链接。

<?php
$xml=simplexml_load_file("http://feeds.foxnews.com/foxnews/latest");
print_r($xml);

?>

该代码打印此

SimpleXMLElement Object ( [@attributes] => Array ( [version] => 2.0 ) [channel] => 
SimpleXMLElement Object ( [title] => FOXNews.com [link] => http://www.foxnews.com/ [description] =>

我缩短了它，因此更容易阅读。完整的是patriotvoice.net。在上面的代码中，我注意到标题是一个SimpleXMLElement对象，我试图使用print_r($xml->item[0]->title);将其打印出来，但它不会打印任何内容。我做错了什么，所以我可以有10 <a href="$link">$title</a>

Answer 1

您必须将叶值转换为字符串。

var_dump((string)$xml->channel->item[0]->title);

如果没有强制转换，它们只代表空的SimpleXMLElement。

Answer 2

试试这个：

$link = $xml->channel->item[37]->link;
$title = $xml->channel->item[37]->title;
print "<a href=\"$link\">$title</a>";

结合关于解析xml的问题
