今天早上，当我试图改进我对某个问题给出的（可能的）解决方案答案时，我遇到了困难。
我尝试将自动生成的标签（使用带有前缀等的唯一命名方案）与文本（甚至数学内容等）一起写入文件，然后通过from.aux使用标签名称引用它。\nameref*nameref
下面的 MWE 简化为基本问题，我创建了一个\WriteMyLabel完成该工作的小命令。
但是我不能写类似的东西
\WriteMyLabel{\textbf{some bold text}}
LaTeX 提供了非常有趣的错误信息
\text@command #1->\def \reserved@a { #1}\ifx \reserved@a \@empty \let \check@...
我该如何解决这个问题？有可能吗？
\documentclass[12pt]{article}
\usepackage{blindtext}%
\usepackage{xcolor}
\usepackage{etoolbox}
\usepackage{hyperref}
\newcounter{TotalLabelCounter}
%%%% A command to make the references clearer, just for debugging, not in
%%%% end production code
\newrobustcmd{\refcommand}[1]{\fbox{\textbf{\textcolor{blue}{\nameref*{#1}}}}}
\makeatletter
\newrobustcmd{\WriteMyLabel}[1]{%
\refstepcounter{TotalLabelCounter}%
\immediate\write\@auxout{%
\string\newlabel{MyLabel::\number\value{TotalLabelCounter}}{{\thesection}{\thepage}{#1}{}}
}% End of writing to AUX file
}%
\makeatother
\begin{document}
\section{First}
\WriteMyLabel{The Three Witches}
\WriteMyLabel{$E = mc^2$}
\blindtext[1]
\newpage
\section{Another section}
\blindtext[1]
\WriteMyLabel{\textbf{some bold text}}
\refcommand{MyLabel::1} from the play 'Macbeth' have a very important part, however, there are no nice formulas such as \refcommand{MyLabel::2} and
it would be better, if \refcommand{MyLabel::3} would work.
\end{document}

哦，这太简单了，想了想：代码必须是\unexpanded;-)
\documentclass[12pt]{scrartcl}

\newrobustcmd{\refcommand}[1]{\fbox{\textbf{\textcolor{blue}{\nameref*{#1}}}}}

\newrobustcmd{\WriteMyLabel}[1]{%
\refstepcounter{TotalLabelCounter}%
\immediate\write\@auxout{%
\string\newlabel{MyLabel::\number\value{TotalLabelCounter}}{{\thesection}{\thepage}{\unexpanded{#1}}{}}
}% End of writing to AUX file
