我发现我可以方便地通过使用 为 KOMA-Script 中的部分添加序言\setpartpreamble。
因此我定义了这样的序言（它应该是一个摘要）：
\documentclass{scrbook}
\begin{document}
\setpartpreamble{This is an abstract.}
\part{First Part}
\end{document}
LaTeX 输出看起来像所需的那样 - 序言位于部分标题下：
但是现在如果我通过 TeX4ht (by make4ht MWE.tex) 生成 HTML，这个序言就不会出现在部分页面上，而是出现在它之前的某个看似随机的位置。
有什么想法可以使 TeX4ht 生成所需的输出？
答案1
似乎在 TeX4ht 重新定义\part命令时，应该在命令末尾执行的钩子在分段文本本身之前执行。此版本scrbook.4ht应该可以修复此问题：
