如何展开maketitle这个命令

我想按遍历顺序抽提出每个latex文档的maketitle这个命令序列所有代码，比如

\documentclass{article}% use option titlepage to get the title on a page of its own.
\usepackage{blindtext}
\title{The Triangulation of Titling Data in Non-Linear Gaussian Fashion via $\rho$ Series\thanks{No procrastination}}
\date{2017\\ December}
\author{John Doe\\ Magic Department\thanks{I am no longer a member of this department}, Richard Miles University 
\and Richard Row, \LaTeX\ Academy}
\begin{document}
\maketitle
\section{Introduction}
\blindtext
\end{document}

这个latex中抽提出的代码是

\title{The Triangulation of Titling Data in Non-Linear Gaussian Fashion via $\rho$ Series\thanks{No procrastination}}
\author{John Doe\\ Magic Department\thanks{I am no longer a member of this department}, Richard Miles University 
\and Richard Row, \LaTeX\ Academy}
\date{2017\\ December}

而另外一个例子：

\documentclass[conference]{IEEEtran}
\usepackage{blindtext}

\begin{document}
\author{
\IEEEauthorblockN{Ying Meng, Jianhai Su, Jason M. O'Kane, Pooyan Jamshidi}
\IEEEauthorblockA{\textit{Departmetn of Computer Science and Engineering} \\
\textit{University of South Carolina}\\
Columbia, SC, USA}
}
\maketitle
\section{Introduction}
\blindtext
\end{document}

这个latex中抽提出的代码是

\title{\Large \bf ATHENA: A Framework based on Diverse Weak Defenses \\ for Building Adversarial Defense}
\author{
\IEEEauthorblockN{Ying Meng, Jianhai Su, Jason M. O'Kane, Pooyan Jamshidi}
\IEEEauthorblockA{\textit{Departmetn of Computer Science and Engineering} \\
\textit{University of South Carolina}\\
Columbia, SC, USA}
}

我想知道这可能实现吗？如果不能按照遍历顺序提取，有没有办法从latex源码中获取maketitle这部分对应的代码呢？
