This is a direct follow-up to tex4ht: custom list of … (part 2 of 3)
I have a custom list of <things>. The code below provides two-way links between the occurrence of the <thing> on the page and its place in the List of cmh.
the question
How can I adapt the solution from the linked question to account for cases in which the argument to \cmhcommand contains either or both of the following:
- multiple paragraphs
- mathematical content
To reproduce the problem in the code below, replace \cmhcommand{Here is some text} with \cmhcommand{Here is some text\par a new paragraph} in mwe.tex.
mwe.tex
\documentclass{article}
\usepackage{cmhloc}
\begin{document}
\tableofcontents
\section{normal section}
\cmhcommand{Here is some text}
some text
\section{another secton}
\cmhcommand{Another text}
\cmhcommand{some more}
\listofcmh
\end{document}

\newcommand{\cmhcommand}[1]{\addcontentsline{cmh}{subsection}{#1}\printcmhentry{#1}}
\newcommand{\listofcmh}{\subsection*{List of cmh}\@starttoc{cmh}}
\endinput

\renewcommand\printcmhentry[1]{%

\edef\cmhlink{cmh-\the\cmhcount}% this will be the id for the corresponding entry in the \listcmh
\csxdef{cmhcn-#1}{\cmhlink}\Link{\cmhlink}{}#1\EndLink} % we use the entry text in csname,
