XML CDATA not returning properly with simplexml_load_string() nor SimpleXMLElement() (PHP)

我可以拉回任何非cdata字段。但不是摘要字段。我已经用尽了我所知道的一切去尝试。下面是我所能得到的最接近的结果，摘要字段返回空白。当然，如果我对整个文件进行var_dump，它确实会返回，但这样我就不能访问特定的字段。请帮助!谢谢!

XML示例

PHP

$str_xml = file_get_contents('http://content.zillow.com/feeds/partners/wsls/');
    $obj_xml = new SimpleXMLElement($str_xml);
    foreach( $obj_xml->children('zatom', true)->entry as $entries ) {
        echo (string) 'Title: ' . $entries->title . '<br />';
            echo (string) 'Summary: ' . simplexml_load_string($entries->summary, null, LIBXML_NOCDATA) . "<br />'n";
    }

您的代码中有一个小问题，simplexml_load_string文档提到:

接受一个格式良好的XML字符串，并将其作为对象返回。

并且提供了一个SimpleXMLElement作为第一个参数。只需将代码中的这一行替换为以下一行:

echo (string) 'Summary: ' . simplexml_load_string($entries->summary->children()->asXML(), null, LIBXML_NOCDATA) . "<br />'n";
