为什么RSS不能处理&符号？ [英] Why can't RSS handle the ampersand?
问题描述
当我遇到一个破碎的RSS提要时，通常的原因是由于第23行说Sanford& Sons。
When I come across a broken RSS feed, the usual reason its all blown to pieces is because line 23 says "Sanford & Sons."
最令人困惑的是，如果将& 转换为& ; amp; ，一切都很好，即使你的替代方案仍然包含问题字符。
The most confusing thing is the fact that if you convert the & into &, all is well, even though your alternative still contains the problem character.
为什么RSS不能渲染&符号（& ）字符默认情况下
Why does RSS fail at rendering the ampersand (&) character by default?
推荐答案
;看到，翻译正在寻找一个有效的逃脱&序列（例如'& amp;'）。当找到无效的序列时，会引发错误。这就是它的一切。
When a 'raw' & is seen, the interpreter is looking for one of the valid escaped & sequences (such as '&' ). When an invalid sequence is found it throws an error. That's all there is to it.
