从rss feed读取cdata [英] read cdata from a rss feed

问题描述

我正在使用简单的代码阅读rss feed:

I'm reading a rss feed using simple code:

 <?php
$homepage = file_get_contents('http://www.forbes.com/news/index.xml');
$movies = new SimpleXMLElement($homepage);
echo '<pre>';
print_r($movies);
?>

和类似这样的输出: SimpleXMLElement对象 ( [@attributes] =>数组 ( [版本] => 2.0 )

and the output like this: SimpleXMLElement Object ( [@attributes] => Array ( [version] => 2.0 )

[channel] => SimpleXMLElement Object
    (
        [title] => SimpleXMLElement Object
            (
            )

        [link] => SimpleXMLElement Object
            (
            )

        [description] => SimpleXMLElement Object
            (
            )

        [language] => en-us
        [copyright] => Copyright 2009 Forbes.com LLC
        [item] => Array
            (
                [0] => SimpleXMLElement Object
                    (
                        [title] => SimpleXMLElement Object
                            (
                            )

                        [link] => SimpleXMLElement Object
                            (
                            )

                        [author] => SimpleXMLElement Object
                            (
                            )

                        [pubDate] => Sat, 05 Nov 2011 07:17:21 GMT
                        [description] => SimpleXMLElement Object
                            (
                            )

                    )

如何读取CDATA值并将其存储在mydatabase中.

how can I read and store CDATA value in mydatabase .

推荐答案

告诉SimpleXML将CDATA转换为普通文本:

Tell SimpleXML to convert CDATA into normal texts:

$homepage = 'http://www.forbes.com/news/index.xml';
$movies = simplexml_load_file($homepage, "SimpleXMLElement", LIBXML_NOCDATA);

应该使用 simplexml_load_file 代替file_get_contents.

相关答案:在simplehtmldom中删除cdata .
