有没有办法可以自动获取每个部分这三个值的值，这样我就不必手动计算了？
There are xxx questions in section A. \\
There are xxx questions in section B. \\
There are xxx questions in section C. \\
我希望做出一个全局性的改变，即在定义之前改变一些内容\开始{文档}所以我不必对已有的每个文件进行更改。
我还应该提到，我必须保持问题编号保持不变。也就是说，它们是不会从每个新的部分*{}重新开始。
谢谢。
答案1
您想要保存qnumber新部分开始时的值（以及文档结束时的值）。
如果您定义自己的命令，则会更容易，因此您还可以享受不需要每次手动格式化的好处。

该.aux文件包含
\relax
\QUESTIONS {0}{0}
\QUESTIONS {1}{3}
\QUESTIONS {2}{2}
\QUESTIONS {3}{3}
\gdef \@abspage@last{2}
您可以看到正确的值已被保存并在下次运行 LaTeX 时使用。
如果你想保留\section*并手动编号部分…将后面的代码替换%% infrastructure为
%% infrastructure
\newcounter{qsection}
\renewcommand{\theqsection}{\Alph{qsection}}
\NewCommandCopy{\latexsection}{\section}
\renewcommand{\section}{%
% save the value of qnumber
\saveqnumber
\stepcounter{qsection}%
\latexsection
}
\AtEndDocument{\saveqnumber}
此后代码相同。
问题计数器未重置的版本。
