在下面的代码中，我想使用\StrGobbleLeft{\ref*{#1}}{2}so 来代替n，#n其中最后的格式用于对链接的特殊脚注进行编号。
\StrGobbleLeft{\ref*{#1}}{2}不起作用。有没有什么办法可以实现我想要的效果？
我具体想要的是……
我想使用带有编号显示的脚注，#n其中 n 是脚注的常用计数器，而井号#用于表示非常特殊的脚注。我将其用于文本中的链接，而不是显示http://www.google.fr/，在文本中，我的宏newUrl会打印类似以下内容的内容：http://link-n/#n其中n是新 URL 的计数器，并且#n是一个脚注，此脚注的内容是完整链接。
我有一个第二个宏oldUrl，可用于重复使用已指示的一个链接，而无需创建新的脚注。我在使用这个第二个宏时遇到了麻烦，我想\ref*{...}将脚注编号的文本附加到与新 URL 关联的脚注文本中的一个标签上。
我的代码
