如何改变 lstset 中 html 标签的颜色？

我有一段代码："></li></a><script>alert(123);</script>我想使用 \lstset 来着色（即 => HTML 标签如“li”“a”“script”将是 dkblue 颜色）。我使用“listings”包和 \lstset 扩展，如下所示：

\lstset{
language        = html,
basicstyle      = \small\ttfamily,
keywordstyle    = \color{dkblue},
stringstyle     = \color{red},
identifierstyle = \color{dkgreen},
commentstyle    = \color{gray},
emph            =[1]{html},
emphstyle       =[1]\color{black},
emph            =[2]{if,and,or,else},
emphstyle       =[2]\color{dkyellow}}

问题在于，在其余代码之前放置“>”会阻止 LaTeX 将代码解释为 HTML。有人有解决方案吗？

您的代码片段颜色正确：它以 a 开头"，因此它是一个字符串。

一个快速而肮脏的（实际上不是很快但相当肮脏）解决方案是从lstlisting没有字符串分隔符的情况下复制 html 驱动程序，然后添加您自己的首选项：

\documentclass{article}
\usepackage{listings,xcolor}
\definecolor{dkgreen}{rgb}{0,.6,0}
\definecolor{dkblue}{rgb}{0,0,.6}
\definecolor{dkyellow}{cmyk}{0,0,.8,.3}
\lstdefinelanguage{nohtml}{

    basicstyle      = \small\ttfamily,
    keywordstyle    = \color{dkblue},
    stringstyle     = \color{red},
    identifierstyle = \color{dkgreen},
    commentstyle    = \color{gray},
    emph            =[1]{html},
    emphstyle       =[1]\color{black},
    emph            =[2]{if,and,or,else},
    emphstyle       =[2]\color{dkyellow}
}
\begin{document}
\begin{lstlisting}[language=nohtml]
"></li></a><script>alert(123);</script>
\end{lstlisting}
\end{document}

结果：

该解决方案的一个优点是，对于其他格式良好的 html，您仍然可以使用默认html定义（带有字符串）。
