列出其他章节的标签

Question

\label我尝试以超链接的形式自动生成相关列表。

我几乎成功地做到了我想要的，使用了这个主题中提出的解决方案：所有带超链接的标签列表

结果如下：

但是我还有两个问题：

第一的：我的超链接列表位于一个章节中，该章节包含在一个包含大量 的文档中\include。 并且似乎没有找到主文件之外的那些，如下例所示。

编辑：找到解决方案后，我将读取.aux 文件的代码放入一个函数中：

\NewDocumentCommand\readauxfile{m}{
\newread\zz
\immediate\openin\zz=#1.aux
\loop
\ifeof\zz\else
\read\zz to \tmp
\expandafter\findlabel\tmp\relax\findlabel
\repeat
}

然后我必须调用它来读取 main.aux 文件

\readauxfile{\jobname}

最后，我\include用一个新\includewithlabels函数替换它，该函数除了包含.tex 之外还读取.aux：

\NewDocumentCommand\includewithlabels{m}{
\readauxfile{./#1}
\include{#1}
}

第二：我用逗号分隔所有超链接，以便获得紧凑的列表。但是最后一个逗号是不需要的。我想知道您是否有办法修复它。

这是主要文件：

\documentclass{book}

\usepackage{xstring} % function IfSubStr to select the labels I want based on kewords
\usepackage{amsthm} % package I use for theorems
\usepackage{thmtools} % package I use for theorems    
\usepackage{hyperref}

% To color the hyperlinks
\hypersetup{
    colorlinks=true,
    linkcolor=blue
}

\newtheorem{theorem}{Theorem}

% If it is a definition of a new label send it to the list
\long\def\findlabel#1#2\findlabel{%
 \ifx\newlabel#1\lablist\expandafter{\the\lablist\showlabel#2}\fi}

% Select the label of it contains the word "relevant" and format the list
\def\showlabel#1#2{\IfSubStr{#1}{relevant}{\hyperref[#1]{#1},}{}}

% Read a .aux file
\NewDocumentCommand\readauxfile{m}{
\newread\zz
\immediate\openin\zz=#1.aux
\loop
\ifeof\zz\else
\read\zz to \tmp
\expandafter\findlabel\tmp\relax\findlabel
\repeat
}

% Read the main.aux file
\readauxfile{\jobname}

% New command we have to use instead of \include
\NewDocumentCommand\includewithlabels{m}{
\readauxfile{./#1}
\include{#1}
}

\begin{document}

\section{A relevant section}\label{relevant section}

A section in the main file.

\includewithlabels{chapter/chapter}

\section{Another section}\label{other section}

We are back in the main file. Let's present an equation and a figure I also want to refer to.

\begin{equation}
1=2\label{relevant equation}
\end{equation}

\begin{figure}[ht]
\centering \huge XXX

\caption{a relevant figure}\label{relevant figure}
\end{figure}

\end{document}

以下是章节：

\section{A relevant included section}\label{relevant included section}

Another file containing another section and the list of every relevant sections, figures, equations...

Here is the list: \the\lablist

%\begin{theorem}
%This theorem causes issues with thmtools and input but works well with inlude.
%\end{theorem}
