我目前正在将我的评论系统恢复为默认的Wordpress评论。我之前使用的是Disqus，但我决定退回去。 Disqus提供了一个可以导出所有注释的工具，但不幸的是，它们将为您提供XML格式。最糟糕的是WordPress只读取WXR文件格式。
我的解决方案是我应该手动重写Disqus给我的东西（我的意思是我从disqus导出的XML文件）到WordPress WXR文件格式。我的问题是我不知道所需的WordPress评论的基本结构是什么。
You can view the Disqus Exported XML file here！ 我唯一关心的是我只需要一个模板或格式，我可以遵循如何编写正确的WXR文件注释，以便我可以使用导入工具直接在我的WordPress中导入它。顺便说一句，当我尝试将XML文件上传到WordPress时，我收到此错误：
文件无效。请上传有效的Disqus导出文件。“

Disqus WordPress插件包含一个同步功能，可以将您的评论从Disqus同步回您的WordPress安装。它可以位于插件内的“高级选项”选项卡上。

可能更容易解析Disqus XML文件并将从中提取的注释直接插入wordpress数据库中的wp_comments表，而不是尝试生成WXR文件格式。至少这样你可以更好地控制过程。
以上插件可能无法正常工作，因为Disqus会不时更改导出格式（奇怪的是，您甚至无法使用导出的文件将评论重新导入Disqus。）
For my service我必须重写两次解析器才能使它适应Disqus XML的小而烦人的变种

你看过这个插件了吗？ http://wordpress.org/extend/plugins/disqus-comments-importer/
它看起来有限但可能是一个很好的起点。

将disqus评论导入我的新网站时遇到同样的问题。 最近我想出了一些方法来解析并将注释插入到wordpress数据库中，所有内容都是用PHP编写的，请参考这个this link，欢迎任何反馈
