引用环境和 tex4ht

我正在尝试转换一些包含引用环境，使用 html乳胶。这里有一个小例子，其排版没有任何问题：

\documentclass{scrbook}
\usepackage{quoting}

\begin{document}
\chapter{Chapter one}
Here is a para

Here is a second para

\begin{quoting}
one para inside a small block.

another para inside the block.
\end{quoting}

Now for a para after the quote.

And another para after the quote.

What has happened? In the HTML version there are no para breaks!

\chapter{Chapter two}
Let's try after a chapter break.

That's good -- para breaks work now.

But what happened after the quoting environment in the previous chapter?
\end{document}

当我尝试在这个文件上运行 htlatex 时，它不知道引用环境，所以我创建了这个 tex4ht 配置文件配置示例.cfg：

\Preamble{html}

\begin{document} 
\ConfigureEnv{quoting}
    {\HCode{<blockquote>}}
    {\HCode{</blockquote>}}{}{}

\EndPreamble

运行这个程序似乎htlatex example.tex "configexample.cfg"有效，并且它创建例子.html，甚至在其中获得了 blockquote 标签。但是在引用环境结束后，我没有得到我期望的 p 标签。也就是说，直到章节中断之后才得到。

我不知道这是 tex4ht 的问题，还是引用包。我可以回到使用引用环境，但如果可以的话，我想先让它工作。有什么想法吗？

（在 MiKTeX 下运行）

好的，看起来这quoting非常积极地重新定义了\everypar用于tex4ht插入<p>标签的令牌寄存器。因此，我们必须创建quoting.4ht将自动加载的文件quoting.sty：

\newtoks\quoting@parht
\NewConfigure{quoting}{2}
\Configure{quoting}
{\ifvmode \IgnorePar\fi \EndP\HCode{<blockquote>}\HtmlParOn}
{\ifvmode \IgnorePar\fi \EndP\HCode{</blockquote>}\HtmlParOn\par}

\ConfigureEnv{quoting}
{\quoting@parht=\everypar%
\a:quoting\par\ShowPar}
{\par%
\b:quoting%
\everypar=\quoting@parht\par\ShowPar}
{}{}

\ConfigureList{quoting}{}{}
{%
\everypar=\quoting@parht\par\ShowPar%
}{}

首先，我们定义新的令牌寄存器quoting@parht，其中\everypar保存了的值，然后quoting创建新的配置，因此我们可以仅配置要插入的标签。

然后\ConfigureEnv我们用 保存 的值\everypar，然后插入开始和结束标记，并恢复 的值everypar，这样 html 段落就会被打印出来。我们还必须使用\ConfigureList，这样段落在环境中也能正常工作。结果：
