在不扩展的辅助文件中写入内容

我正在从目录文件创建 XML，在此过程中我发现了问题。查看文件时发现许多命令在写入时被扩展。例如，在\hat中写入 。当我之前\mathaccentV {tilde}251{A}使用时，它在目录中写入 \hat。有没有什么方法可以在不扩展的情况下在目录中生成相同的内容\protect\hat

\documentclass{book} 
\begin{document} 
\chapter{This is a sample chapter $\hat{z}acffr$} 
\section{This is a sample section $\tilde{d}$} 
\end{document}

Aux 文件内容：

\relax 
\@writefile{toc}{\contentsline {chapter}{\numberline {1}This is a sample chapter $\mathaccent "705E\relax {z}acffr$}{1}}
\@writefile{lof}{\addvspace {10\p@ }}
\@writefile{lot}{\addvspace {10\p@ }}
\@writefile{toc}{\contentsline {section}{\numberline {1.1}This is a sample section $\mathaccent "707E\relax {d}$}{1}}

我没有尝试更改实际的aux和toc文件，而是只编写了一个附加文件，fauxtoc.toc它模仿 toc 文件，但未扩展。

\chapter此版本针对和实施\section，因为这是 OP 所提到的。可以添加其他部分。

该方法借鉴了egreg对这个问题的回答：将 \\ 写入文件

\documentclass{book}
\usepackage{xpatch}
\makeatletter
\let\protected@iwrite\protected@write
\xpatchcmd{\protected@iwrite}{\write}{\immediate\write}{}{}
\let\svchapter\chapter
\let\svsection\section
\renewcommand\chapter{\@ifstar{\svchapter*}{\mychapnostar}}
\newcommand\mychapnostar[2][]{%
  \ifx\relax#1\relax\svchapter{#2}\fauxtocwrite{chapter}{\thechapter}{#2}%
  \else\svchapter[#1]{#2}\fauxtocwrite{chapter}{\thechapter}{#1}\fi%
}
\renewcommand\section{\@ifstar{\svsection*}{\mysectnostar}}
\newcommand\mysectnostar[2][]{%
  \ifx\relax#1\relax\svsection{#2}\fauxtocwrite{section}{\thesection}{#2}%
  \else\svsection[#1]{#2}\fauxtocwrite{section}{\thesection}{#1}\fi%
}
\newcommand\fauxtocwrite[3]{%
    \edef\tmpA{\thepage}%
    \protected@iwrite\tempfile{}{\detokenize{\contentsline{#1}}%
      {\detokenize{\numberline}{#2}\detokenize{#3}}{\tmpA}}%
}
\makeatother
\newwrite\tempfile
\AtBeginDocument{\immediate\openout\tempfile=fauxtoc.toc}
\AtEndDocument{\immediate\closeout\tempfile}
\begin{document}
\tableofcontents
\chapter{Sample chapter $\hat{z}acffr$} 
\chapter[$\hat{z}acffr$]{Next}
\section{This is a sample section $\tilde{d}$} 
\end{document}

这将生成一个文件fauxtoc.toc，该文件与正确的 toc 文件匹配，只是部分名称未展开

normal.toc：

\contentsline {chapter}{\numberline {1}Sample chapter $\mathaccent "705E\relax {z}acffr$}{3}
\contentsline {chapter}{\numberline {2}$\mathaccent "705E\relax {z}acffr$}{5}
\contentsline {section}{\numberline {2.1}This is a sample section $\mathaccent "707E\relax {d}$}{5}

fauxtoc.toc：

\contentsline {chapter}{\numberline {1}Sample chapter $\hat {z}acffr$}{3}
\contentsline {chapter}{\numberline {2}$\hat {z}acffr$}{5}
\contentsline {section}{\numberline {2.1}This is a sample section $\tilde {d}$}{5}
