PHP SimpleXMLElement - 无法从 Feed 中检索 'Description' 元素

Question

我不太了解如何抓取 XML 文档。可能有点误会。

供稿 URL：http://www.simplifyingthemarket.com/feed/

代码：-

$url = 'http://www.simplifyingthemarket.com/feed/';
$XmlObject = new SimpleXmlElement( file_get_contents($url) );
print_r($XmlObject->channel[0]->item[0]->description[0]);

输出：-

SimpleXMLElement Object ( )

要求的输出：-

<a href="http://www.simplifyingthemarket.com/wp-content/uploads/2015/04/Where-Should-I-Retire.jpg"><img class="alignnone wp-image-30608" src="http://www.simplifyingthemarket.com/wp-content/uploads/2015/04/Where-Should-I-Retire.jpg" alt="Where Should I Retire [INFOGRAPHIC] &#124; Simplifying The Market" width="600" height="1035" /></a>

为了以字符串形式访问节点的值，您首先必须将其转换为字符串。在你的情况下它会是这样的：

print_r((string) $XmlObject->channel[0]->item[0]->description[0]);
