![转义特殊字符以用作 URL](https://linux22.com/image/309846/%E8%BD%AC%E4%B9%89%E7%89%B9%E6%AE%8A%E5%AD%97%E7%AC%A6%E4%BB%A5%E7%94%A8%E4%BD%9C%20URL.png)
如果网址包含特殊字符(~
和#
),则将其用作
\href{http://people.brunel.ac.uk/~mastmmg/ssguide/set_work.html#4_32}{people.brunel.ac.uk}
运行正常。但是,我希望有一个包含这些 URL 的宏列表,并在稍后处理它们,就像我在使用 \foreach 循环执行宏,宏的参数以列表形式提供。因此,我希望能够这样说:
\DefineMyFormatLinkParameters{%
*[Main Search Site]{Google}{http://www.google.com},
[people.brunel.ac.uk]{http://people.brunel.ac.uk/~mastmmg/ssguide/set_work.html#4_32},
{Yahoo}{http://www.yahoo.com}
}
随着冒犯性评论的出现,我得到了:
对于第一种和第三种情况,这种方法很有效,但对于带有特殊 TeX 字符的情况,这种方法就不行了。我尝试过转义这些字符,但效果并不好,因为链接无法点击。
那么,我不知道该如何转义此类列表中的特殊字符?

Following should produce same results as above:\medskip\par
\foreach \x in \MyFormatLinkParameters {%
\typeout{DEBUG: "\x"}
\expandafter\FormatLinks\x
}
