php - 如何在php中使用cdata将xml文件转换为json格式？

Question

我正在尝试将我的 xml 文件（大文件）转换为 php 中的 json 格式。问题是 json 格式的 cdata 丢失。

这是我的代码，

<?php
$xml = simplexml_load_file('belovedskincare.xml', 'SimpleXMLElement', LIBXML_NOCDATA);
$jsondata = json_encode($xml);
echo $jsondata;
?>

XML 代码：

This XML file does not appear to have any style information associated with it. The document tree is shown below.
<!--  This is a WordPress eXtended RSS file generated by WordPress as an export of your site.  -->
<!--  It contains information about your site's posts, pages, comments, categories, and other content.  -->
<!--  You may use this file to transfer that content from one site to another.  -->
<!--  This file is not intended to serve as a complete backup of your site.  -->
<!--  To import this information into a WordPress site follow these steps:  -->
<!--  1. Log in to that site as an administrator.  -->
<!--  2. Go to Tools: Import in the WordPress admin panel.  -->
<!--  3. Install the "WordPress" importer from the list.  -->
<!--  4. Activate & Run Importer.  -->
<!--  5. Upload this file using the form provided on that page.  -->
<!--  6. You will first be asked to map the authors in this export file to users  -->
<!--     on the site. For each author, you may choose to map to an  -->
<!--     existing user on the site or to create a new user.  -->
<!--  7. WordPress will then import each of the posts, pages, comments, categories, etc.  -->
<!--     contained in this file into your site.  -->

但实际输出应该是，

如您所见，“通道”属性包含的数据非常少。并且通过实际输出，您可以看到它包含更多数据。由于它是一个大文件，我插入了一小部分输出。我希望这么多的输出就足够了。如果您想了解更多详细信息，请在评论中提及。如果可能的话，我会插入它。
