从rss feed中读取cdata

Question

我正在使用简单的代码阅读RSS订阅源:

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

和输出如下: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
                            (
                            )

                    )

如何在mydatabase中读取和存储CDATA值.

Answer 1

告诉SimpleXML将CDATA转换为普通文本:

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

这应该为你做,simplexml_load_file而不是使用file_get_contents.

相关解答:在simplehtmldom中删除cdata.
