我需要為一個會議處理大約 100 個 tex 檔。每個文件都包含簡報的摘要，並且有一位作者。讓我們假設每個檔案的相關部分是以下 TeX 或 LaTeX 巨集（指令或環境）的參數：
TITLE% 論文標題
AUTHOR% 作者（給出為：LastName、FirstName）
AFFILIATION% 作者的單位（包括電子郵件地址）
ABSTRACT% 演講摘要
REFERENCES% 引入的參考文獻的簡短列表\bibitem
我想獲得一份文檔，其中包含按作者姓氏排序的簡報摘要，以及目錄和包含其隸屬關係的參與者排序清單。
我想到首先剝離作者提交的tex文件，只留下相關信息（上面提到的），但我不知道下一步應該如何進行，以“算法”的方式（沒有任何手動排序或其他“手動”） “方法）。
我看過類似的問題這裡，但我找不到排序問題的解決方案。

同時，我已經部分解決了問題，除了整理部分，想和大家分享一下，期待大家提出寶貴的意見和建議。
我選擇進行“外部”排序並將結果直接貼到主 tex 檔案中，因為它似乎是最簡單的選項。我想過使用datatool捆綁包，但使用 TeX 之外的簡單文字排序只花了我幾秒鐘。
數據是使用具有以下結構的簡單文本文件從作者收集的：
\AUTHOR{}{} %% <--- {LastName}{FirstName}
\EMAIL{}
\AFFILIATION{}
\TITLE{}
\ABSTRACT{}
主檔案讀取這些檔案並產生摘要書的內容，如下面的最小範例（其中我們讀取三個檔案），其中巨集在外部檔案中定義abstractbook.sty：
\documentclass[a4paper,12pt]{article}
\usepackage{abstractsbook}
\begin{document}
%% ++++++++++ Process submitted files ++++++++++++++++++
\begin{processfiles}
%% ---------------------------------------
\processfile{FirstAuthor}
\processfile{SecondAuthor}
\processfile{ThirdAuthor}
%% First sorted alphabetically outside TeX
\end{processfiles}
\parindent 0pt
%% +++++++++++++++++++ List of Talks ++++++++++++++++++
\listoftalks
%% +++++++++++++++++++ Abstracts ++++++++++++++++++++++
\abstracts
%% +++++++++++++++++++ Index of participants +++++++++++
\listofparticipants
%% +++++++++++++++++++++++++++++++++++++++++++++++++++++
\end{document}
該abstractbook.sty文件定義了上述所有巨集。處理文件時，從與主 tex 檔相同的資料夾中\processfile{NameOfFile}讀取內容。NameOfFile.tex每個\processfile{...}增加一個本機計數器（計算讀取檔案的數量）並定義以下巨集：
\author-<x>-LastName
\author-<x>-FirstName
\affiliation-<x>
\email-<x>
\title-<x>
\abstract-<x>
其中<x>是計數器的當前值。
在排版文件時，我們只需循環遍歷計數器的所有值並顯示所需的資訊。
請參閱下面的一個最小範例abstractbook.sty。我希望它（不那麼難）可讀：

另請考慮以下摘要文件的最小範例：
FirstAuthor.tex
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\AUTHOR{First}{Author}% <--- {LastName}{FirstName}
%%
\EMAIL{[email protected]}
%%
\AFFILIATION{First University}
%%
\TITLE{The first title}
%%
\ABSTRACT{This is the abstract of the first talk.
And some math: $1+1=2$.
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
SecondAuthor.tex
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\AUTHOR{Second}{Author}% <--- {LastName}{FirstName}
%%
\EMAIL{[email protected]}
%%
\AFFILIATION{Second University}
%%
\TITLE{The second title}
%%
\ABSTRACT{This is the abstract of the second talk.
And some math:
\[
E=m\mathrm{c}^2.
\]}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
ThirdAuthor.tex
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\AUTHOR{Third}{Author}% <--- {LastName}{FirstName}
%%
\EMAIL{[email protected]}
%%
\AFFILIATION{Third University}
%%
\TITLE{The third title}

\ABSTRACT{This is the abstract of the second talk.
And some math:
