简短的回答是将URL编码,就像在文档中编码任何其他文本一样。如果您按照以下方式替换字符,就不会出错:
& -> &
-> '
" -> "
< -> <
> -> >
(使用符合规范的解析器阅读文档的任何人都将获得正确的、即未编码的文本。)
然而,我想重申Anthony的评论:为什么你认为你需要担心这个问题?任何明智的XML编写系统都应该将你想要表示的文本进行编码(就像解析器将撤销编码一样)。你的应用程序只需处理未编码的文本,它应该依赖于XML编写库来处理字符编码和保留规范性。否则,你会冒着被称为傻瓜的风险。看起来,XmlTextWriter是 .net API,可以进行所有必要的更改。
AntiXSS 库有一个 XmlEncode 方法,您可以使用。
