 Any code html is valid here like &npsb; 
 and what ever you want to transfer]]>

I don't think there's a standard here - it's all about what the RSS reader itself is willing to implement. So my guess would be that, for example, Google Reader would wash out tags and the like and dangerous HTML and CSS attributes, and then allow whatever other sort of non-blacklisted tag you would dare to include.

我认为这里没有标准 - 这完全取决于RSS阅读器本身愿意实现的内容。所以我的猜测就是,例如,Google Reader会清除标签之类的内容以及危险的HTML和CSS属性,然后允许您敢于包含的任何其他类型的非黑名单标记。

So, yeah. There's no specification, and therefore likely no standard - just the same general XSS prevention techniques we see across the whole interwebs. Your only option is to try out various tags that you think may be contentious (though really I'd expect almost anything but CSS styling would be permitted) in different RSS readers to see what happens, or simply to have your content ready to fall back to a more basic format if the desired HTML/CSS is not permitted.

是的。没有规范,因此可能没有标准 - 只是我们在整个互联网上看到的相同的一般XSS预防技术。你唯一的选择是在不同的RSS阅读器中尝试各种你认为可能引起争议的标签(虽然我几乎可以期待除CSS样式之外几乎所有的东西),看看会发生什么,或者只是让你的内容准备回落如果不允许使用所需的HTML / CSS,则为更基本的格式。

What in particular are you trying to do? You may be able to get better answers if you can specify - or is this just a question of curiosity?

你特别想做什么?如果你能指明,你可能会得到更好的答案 - 或者这只是好奇心的问题?

I think the 'right' thing to do is either include an xhtml namespace (xmlns:html="http://www.w3.org/1999/xhtml") or put the HTML data in a CDATA section.

我认为'正确'的做法是要么包含一个xhtml命名空间(xmlns:html =“http://www.w3.org/1999/xhtml”),要么将HTML数据放在CDATA部分。

I don't think there's any "official" answer. It might depend on what level of compatibility you're aiming for.

我不认为有任何“官方”答案。这可能取决于您的目标兼容性程度。

I'd keep it to the basic text formatting tags (STRONG, EM, etc) and IMG and A and that's about it.

我将它保留到基本的文本格式化标签(STRONG,EM等)和IMG和A,这就是它。

In fact, no HTML attributes are allowed in RSS feeds. Only XML tags listed in the specification posted above are allowed. Also, since it is XML, only some Unicode encodings are allowed (e.g. UTF-8). That many RSS providers do not respect the standard is another matter.

实际上,RSS源中不允许使用HTML属性。只允许上面发布的规范中列出的XML标记。此外,由于它是XML,因此只允许一些Unicode编码(例如UTF-8)。许多RSS提供商不尊重标准是另一回事。
