如何将文章的作者写入文件？

我有一个宏\writetitletofile，可以将文章标题写入文件.dat。我怎样才能对文章的作者执行相同的操作。需要注意的是，作者列表是使用authblk包创建的。

\documentclass{scrartcl}
    \usepackage{fontspec, polyglossia}
    \setmainlanguage{english}
    \setmainfont{CMU Serif}                 
    \setsansfont{CMU Sans Serif}            
    \setmonofont{CMU Typewriter Text}
    \usepackage{authblk}
    \author[1]{First Author}
    \affil[1]{Affiliation of the 1st author}
    \author[2]{Second Author}
    \affil[2]{Affiliation of the 2nd author}    
    \title{Title of the article}    
    \makeatletter
    \def\writetitletofile{%
      \newwrite\file
      \immediate\openout\file=titleauthors.dat
      \immediate\write\file{\@title}%
      \immediate\closeout\file%
    }%
    \makeatother        
\begin{document}
\writetitletofile
\end{document}

我们可以利用以明确定义的格式保存作者和所属机构列表的事实authblk：在示例中，宏\AB@authors扩展为

\protect \Authfont \protect \AB@setsep First Author\protect \\[\affilsep ]%
\protect \Affilfont Affiliation of the 1st author\protect \and \protect
\Authfont \protect \AB@setsep Second Author\protect \\[\affilsep ]%
\protect \Affilfont Affiliation of the 2nd author.

（已重新格式化，以便更加清晰）。

\AB@setsep因此我们可以使用递归宏来提取和之间的数据\protect。

\documentclass{scrartcl}
\usepackage{fontspec, polyglossia}
\usepackage{authblk}

\setmainlanguage{english}
\setmainfont{CMU Serif}                 
\setsansfont{CMU Sans Serif}            
\setmonofont{CMU Typewriter Text}

\makeatletter
\newwrite\titleauthorfile
\newcommand\writedatatofile{%
  \immediate\openout\titleauthorfile=\jobname-titleauthors.dat
  \immediate\write\titleauthorfile{\@title}%
  \processauthors
  \immediate\closeout\titleauthorfile
}
\newcommand\processauthors{%
  \expandafter\process@authors\AB@authors\AB@setsep\protect\@nil
}
\def\process@authors#1\AB@setsep#2\protect#3\@nil{%
  \ifx\relax#2\relax
    \expandafter\@gobble
  \else
    \immediate\write\titleauthorfile{\unexpanded{#2}}%
    \expandafter\@firstofone
  \fi
  {\process@authors#3\@nil}%
}
\makeatother        


\author[1]{First Author}
\affil[1]{Affiliation of the 1st author}
\author[2]{Second Author}
\affil[2]{Affiliation of the 2nd author}    
\title{Title of the article}    
\begin{document}
\writedatatofile
\end{document}

该文件的内容\jobname-titleauthors.dat（\jobname是主文件的名称，最好使用依赖于它的名称）将是

Title of the article
First Author
Second Author

为了连续读取创建的文件，最好添加一些结构：

\documentclass{scrartcl}
\usepackage{fontspec, polyglossia}
\usepackage{authblk}

\setmainlanguage{english}
\setmainfont{CMU Serif}                 
\setsansfont{CMU Sans Serif}            
\setmonofont{CMU Typewriter Text}

\makeatletter
\newwrite\titleauthorfile
\newcommand\writedatatofile{%
  \immediate\openout\titleauthorfile=\jobname-titleauthors.dat
  \immediate\write\titleauthorfile{%
     \string\thispapertitle{\unexpanded\expandafter{\@title}}}%
  \processauthors
  \immediate\write\titleauthorfile{\string\finishauthors}
  \immediate\closeout\titleauthorfile
}
\newcommand\processauthors{%
  \expandafter\process@authors\AB@authors\AB@setsep\protect\@nil
}
\def\process@authors#1\AB@setsep#2\protect#3\@nil{%
  \ifx\relax#2\relax
    \expandafter\@gobble
  \else
    \immediate\write\titleauthorfile{%
      \string\thispaperauthor{\unexpanded{#2}}%
    }
    \expandafter\@firstofone
  \fi
  {\process@authors#3\@nil}%
}
\makeatother        


\author[1]{First Author}
\affil[1]{Affiliation of the 1st author}
\author[2]{Second Author}
\affil[2]{Affiliation of the 2nd author}    
\title{Title of the article}    
\begin{document}
\writedatatofile
\end{document}

现在输出文件将是

\thispapertitle{Title of the article}
\thispaperauthor{First Author}
\thispaperauthor{Second Author}
\finishauthors

在对和\input给出合理的定义后，您就可以得到这个文件。\thispapertitle\thispaperauthor
