无效的XML:行出错。实体名称必须紧跟在实体引用中的'&‘后面

Question

我正在尝试将此文件上传到iTunes，但我总是收到相同的错误。在这一点上，我甚至没有任何&，当我通过W3School的验证器运行它时，它说一切都很好。

Answer 1

根据official iTunes podcast specs的规定，“游戏和爱好”这一类别必须在RSS feed中包含一个等同于“&”的HTML实体。在您的特定情况下，使用单词"and“而不是”与“并不对应于任何现有的iTunes类别(因此，iTunes中的错误)。只需将其替换为：

  Games & Hobbies

此外，考虑到视频游戏是游戏和爱好的子类别，因此在播客RSS提要中iTunes类别标签的正确sintax是：

<itunes:category text="Games &amp; Hobbies">
<itunes:category text="Video Games" />
</itunes:category>
