播客 RSS 源中的"XML parsing error: <unknown>:2:0: unbound prefix"

Question

我正在尝试使用自己编写的RSS提要自行发布我的播客。当我检查它是否在https://validator.w3.org/feed/我一直在标题中得到错误，它说错误在第2行，RSS标签本身。我一遍又一遍地检查了代码，并将其与有效的RSS源进行了比较，结果完全相同，所以我不知道问题是什么，w3也没有给我任何解决问题的指示

<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0"
xmlns:media="http://search.yahoo.com/mrss/"
xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd"
xmlns:dcterms="http://purl.org/dc/terms/"
xmnls:spotify="https://www.spotify.com/ns/rss"
xmlns:atom="http://www.w3.org/2005/Atom">

如果有人能告诉我我做错了什么，以及如何修复它，以便feed能够验证，我将不胜感激。

编辑以包含完整代码：

编辑2：多亏了下面kjhughes的帮助，我能够解决RSS标签中的错误(这是一个拼写错误(，然后w3能够在我的代码中发现更多的错误，一旦它们都被修复，它就会得到验证。我会发布经过验证的RSS提要代码，供其他可能有类似问题的人参考：

Answer 1

一般

必须声明所有以使用为前缀的XML命名空间。

具体来说，文档中的每个XML元素名称都带有表单

nspref:LocalName

必须像这个一样声明

xmlns:nspref="http://example.com/ns"

在该元素或其祖先处用于CCD_ 1名称空间前缀。

---

在您的情况下

其中一个名称空间声明中有一个拼写错误：

xmnls:spotify="https://www.spotify.com/ns/rss"
^^

应该是

xmlns:spotify="https://www.spotify.com/ns/rss"
^^

是的，在解决了这样一个问题之后，其他问题可能会被发现。
