是否有必要为HTML EN code右尖括号？ [英] Is it necessary to html encode right angle brackets?

问题描述

我添加一些元数据的描述我的头，像这样：

I'm adding some meta description data to my header like so:

HtmlMeta meta = new HtmlMeta();
meta.Name = "description";
meta.Content = description; // this is unencoded
page.Header.Controls.Add(meta);

和.NET有益EN codeS之类的东西和放大器;和＆lt;，而不是>。现在，我无法想象，这将是一个疏忽，所以我断定，这是不必要的逃避它们。但在此之前我回去与回答客户端，这将是很好，首先通过获取一些陌生人从Intarwebs确认：）

And .net helpfully encodes things like & and <, but not >. Now, I can't imagine that this would be an oversight, so I conclude that it's unnecessary to escape them. But before I go back to the client with that answer, it would be nice to get confirmation by Some Strangers From The Intarwebs first :)

推荐答案

按照XML规范 ＆GT; 确实是有效的属性。只有＆LT; ，＆安培; 和或 需要转义。

According to the XML specification > is indeed valid for attributes. Only <, & and " or ' need escaping.

[10]    AttValue    ::=    '"' ([^<&"] | Reference)* '"'
                         | "'" ([^<&'] | Reference)* "'"
