Question

我有这个XML文件：

http://www.dailymotion.com/rss/tag/house

我需要获得第一个标题和描述项目的内容。比我使用这段代码：

$xml = simplexml_load_file('http://www.dailymotion.com/rss/tag/house/', 'SimpleXMLElement', LIBXML_NOCDATA);

$dom = new DOMDocument();
echo $xml->channel->item->title . "<br>";
@$dom->loadHtml($xml->channel->item->description);

$xpath = new DOMXPath($dom);
echo $description = $xpath->evaluate("string(//p[1]/text())");

这是OUTPUT

Fabio Lenzi - Beautiful Sorrow (Ivan Scratchin Funky Mix)
Download:

但如果我读了xml，在描述项中我会在p tag中找到这个内容：

比我注意到解析从＆lt; br＆gt;标签。如何忽略br标签和其他段落中包含的任何标签？任何帮助它真的很感激。

Answer 1

使用strip_tags删除html代码！

示例：

$stripped_string = strip_tags($unstripped_string, $allowable_tags);

Answer 2

这可能是，

$x = // Your Result;

echo strip_tags($x,'<p>');

从XML with PHP获取描述项并忽略br标签
