如何提取作者姓名

我正在和一位朋友一起写项目报告。问题是，在某个地方（例如titlepage），我需要写下我们所有的详细信息，但在某个地方我只需要姓名。

以下是我想做的事情：

\documentclass{article}
\makeindex
\title{}
\author{Author 1 (Registration Number: XXXX, Email: XXXX) \\ \& Author 2 (Registration Number: YYYY, Email: YYYY)}
\begin{document}

% Title page contains the name and other details
\maketitle \clearpage
\section{Introduction}

\section*{Declaration}
% But, here I need only names and registration numbers separately
We, {\it the~authors individually} declare something.
\\
\\
\begin{minipage}[t]{0.5\linewidth}
Signature of Author 1 (Name only)\\ \\ \rule[0em]{15em}{0.5pt} \\ (Registration of Author 1) \\ \\ Date \\ \rule[0em]{15em}{0.5pt}

\end{minipage}%
\hfill
\begin{minipage}[t]{0.5\linewidth}
Signature of Author 2 (Name only)\\ \\ \rule[0em]{15em}{0.5pt} \\ (Registration of Author 2) \\ \\ Date \\ \rule[0em]{15em}{0.5pt}
\end{minipage}
\end{document}

有没有自动化的方法可以实现这一点？

此外，我还有一个问题：如何在签名和日期上添加虚线？

像这样：

声明两个命令如\FirstAuthor和\SecondAuthor，分别包含 的名称。

\documentclass{article}

\newcommand{\FirstAuthor}{John Doe}%
\newcommand{\SecondAuthor}{Jane Doe}%
\makeindex
\title{}
\author{\FirstAuthor (Registration Number: XXXX, Email: XXXX) \\ \& \SecondAuthor (Registration Number: YYYY, Email: YYYY)}
\begin{document}

% Title page contains the name and other details
\maketitle \clearpage
\section{Introduction}

\section*{Declaration}
% But, here I need only names and registration numbers separately
We, {\it the~authors individually} declare something.
\\
\\
\begin{minipage}[t]{0.5\linewidth}
Signature of \FirstAuthor \\ \\ \rule[0em]{15em}{0.5pt} \\ (Registration of \FirstAuthor) \\ \\ Date \\ \rule[0em]{15em}{0.5pt}

\end{minipage}%
\hfill
\begin{minipage}[t]{0.5\linewidth}
Signature of \SecondAuthor \\ \\ \rule[0em]{15em}{0.5pt} \\ (Registration of \SecondAuthor) \\ \\ Date \\ \rule[0em]{15em}{0.5pt}
\end{minipage}
\end{document}

编辑其他版本，只需一个\NameAuthor[]命令：

\documentclass{article}
\usepackage{etoolbox}%


\newcommand{\NameAuthor}[1][3]{%
\ifnumequal{#1}{1}{%
John Doe}{Jane Doe}%
}%

\makeindex
\title{}
\author{\NameAuthor[1] (Registration Number: XXXX, Email: XXXX) \\ \& \NameAuthor{2} (Registration Number: YYYY, Email: YYYY)}
\begin{document}

% Title page contains the name and other details
\maketitle \clearpage
\section{Introduction}

\section*{Declaration}
% But, here I need only names and registration numbers separately
We, {\it the~authors individually} declare something.
\\
\\
\begin{minipage}[t]{0.5\linewidth}
Signature of \NameAuthor[1] \\ \\ \rule[0em]{15em}{0.5pt} \\ (Registration of \NameAuthor[1]) \\ \\ Date \\ \rule[0em]{15em}{0.5pt}

\end{minipage}%
\hfill
\begin{minipage}[t]{0.5\linewidth}
Signature of \NameAuthor[2] \\ \\ \rule[0em]{15em}{0.5pt} \\ (Registration of \NameAuthor[2]) \\ \\ Date \\ \rule[0em]{15em}{0.5pt}
\end{minipage}
\end{document}

的第一个参数\NameAuthor是可选的，默认为1，即第一作者。\NameAuthor[1]无论如何，我使用了，以明确用法。

另一个更复杂的版本，使用*.bib数据库和用户定义的引用样式。伪造的作者条目可以位于*.bib文档中已经使用的任何文件中，只要与条目键（如）不一致author1, author2,...，但这种情况不太可能发生。

authorextract.cbx首先在文件中定义 citationstyle

\ProvidesFile{authorextract.cbx}%
\RequireCitationStyle{authoryear}% Change if needed to other style
\newbibmacro{year}{\printfield{year}}%
\DeclareCiteCommand{\namecite}[]{}{\usebibmacro{author}}{}{}%
\DeclareCiteCommand{\mailcite}[]{}{\usebibmacro{title}}{}{}%
\DeclareCiteCommand{\regcite}[]{}{\usebibmacro{year}}{}{}%
\endinput%

接下来是作者的条目docauthors.bib：

@BOOK{author1,
  author={John Doe},
  volume={XXXX},
  title={\makeatletter [email protected]\makeatother},
  year={XXXX},
  options={skipbib=true},
}



@BOOK{author2,
  author={Jane Doe},
  year={YYYY},
  title={\makeatletter [email protected]\makeatother},
  options={skipbib=true},
}

@BOOK{author3,
  author={Julius Caesar},
  year={QQQQ},
  title={\makeatletter [email protected]\makeatother},
  introduction={Beware the Ides of March},
  options={skipbib=true},
}


@BOOK{author4,
  author={Will Shake},
  year={ZZZZ},
  title={\makeatletter [email protected]\makeatother},
  introduction={I did honestly wrote all plays by myself},
  options={skipbib=true},
}

这个skipbib=true选项很重要，否则所有引用都会出现在参考书目中-->这里不需要！

现在*.tex代码

\documentclass{article}
\usepackage{etoolbox}%
\usepackage[citestyle=authorextract,backend=bibtex]{biblatex}
\bibliography{docauthors}%


\newrobustcmd{\NameAuthor}[1][4]{%
\namecite{author#1}%
}%

\newrobustcmd{\MailAuthor}[1][5]{%
\mailcite{author#1}%
}%
\newrobustcmd{\RegAuthor}[1][6]{%
\regcite{author#1}%
}%

\newrobustcmd{\AuthorInformationExtraction}[1][7]{%
\NameAuthor[#1] (Registration Number: \RegAuthor[#1], Email: \MailAuthor[#1])
}%

\newrobustcmd{\AuthorInformation}{%
\AuthorInformationExtraction[1] \\ \& 
\AuthorInformationExtraction[2] \\ \&
\AuthorInformationExtraction[3] \\ \&
\AuthorInformationExtraction[4]%
}%

\makeindex
\title{}
\author{%
\AuthorInformation%
}%
\begin{document}
% Title page contains the name and other details
\maketitle \clearpage
\section{Introduction}

\section*{Declaration}
% But, here I need only names and registration numbers separately
We, {\it the~authors individually} declare something.
\\
\\
\begin{minipage}[t]{0.5\linewidth}
Signature of \NameAuthor[1] \\ \\ \rule[0em]{15em}{0.5pt} \\ (Registration of \NameAuthor[1]) \\ \\ Date \\ \rule[0em]{15em}{0.5pt}

\end{minipage}%
\hfill
\begin{minipage}[t]{0.5\linewidth}
Signature of \NameAuthor[2] \\ \\ \rule[0em]{15em}{0.5pt} \\ (Registration of \NameAuthor[2]) \\ \\ Date \\ \rule[0em]{15em}{0.5pt}
\end{minipage}

\printbibliography
\end{document}

我“滥用”了数据库的author、title和year字段，.bib分别存储author name、mail adress和registration数字。稍后，\namecite、\mailcite和\regcite用于这些情况，例如authorextract.cbx。使用\NameAuthor[]与上一个代码版本和 相同的方法\AuthorInformation用于\author{...}块。

使用以下方式编译

pdflatex foo.tex biblatex foo pdflatex foo.tex

是吗，您期望什么？

\documentclass{article}

\def\authorA{Author 1}  \def\regauthorA{(Registration Number: XXXX, Email: XXXX)}
\def\authorB{Author 2}  \def\regauthorB{(Registration Number: YYYY, Email: YYYY)}

\makeindex
\title{}
\author{\authorA\ \regauthorA \\ \& \authorB\ \regauthorB}
\begin{document}

% Title page contains the name and other details
\maketitle \clearpage
\section{Introduction}

\section*{Declaration}
% But, here I need only names and registration numbers separately
We, {\it the~authors individually} declare something.
\par\bigskip

\noindent\begin{minipage}[t]{0.5\linewidth}
Signature of \authorA\ (Name only)\par\bigskip \rule[0em]{15em}{0.5pt} \\
(Registration of \authorA) \par\bigskip Date \par \rule[0em]{15em}{0.5pt}

\end{minipage}%
\hfil
\begin{minipage}[t]{0.5\linewidth}
Signature of \authorB\ (Name only)\par\bigskip \rule[0em]{15em}{0.5pt} \\
(Registration of \authorB) \par\bigskip Date \par \rule[0em]{15em}{0.5pt}
\end{minipage}%
\end{document}

注意：我对您的代码做了一些小改动，以避免盒子过满/过满。
