LaTeX 列表 - 如何将样式应用于不同于内容的分隔符

如何修改键值选项

\lstdefinelanguage{mybnf}{
  morestring   = [b]''
}

得到以下结果：

在此处输入图片描述

也就是说，能够以与内容不同的样式（在本例中是不同的颜色）定义分隔符？

以下是我的 MWE：

好吧，由于某种原因，我错过了一个相关的问答：强调（颜色）列表中两个分隔符之间的内容，但不强调分隔符本身其中包含了我部分问题的答案。因此，我对 MWE 进行了如下修改：

\documentclass{article}
\usepackage{fontspec}
\usepackage{longtable, booktabs}
\usepackage{listings, listings-ext, listingsutf8}
\usepackage[
                usenames,%
                svgnames,%
                dvipsnames,%
                x11names]{xcolor}

不过，正如您所看到的，仍然存在一些问题：

  • 起始分隔符后面是一个非常讨厌的空格，我无法弄清楚为什么，即使当我运行从所提问题的解决方案中获取的片段时，一切正常；
  • 双引号和单引号一旦定义为分隔符，就不能用作常规文本。

有什么想法吗？谢谢
