（这与将文件中包含的文本注入自定义环境，但我被要求将其放在单独的帖子中）
从列表中的正则表达式以下代码运行良好：
\documentclass{report}
\usepackage{listings,xcolor}
\lstdefinelanguage{text}{}
{\catcode`\^^M=12 \def\marshal{\lstnewenvironment{mylang}{\lstset{language=text,comment=[s]{^^MXYZ}{^^M^^M},commentstyle=\color{green},basicstyle=\footnotesize\ttfamily,showstringspaces=false,showspaces=false,}}{}}\expandafter}\marshal
\begin{document}
\begin{mylang}
Only a test, this is not a comment
XYZ this should colored as a comment
and this line too
this is not a command, because only lines starting with XYZ
are comments
This is not a comment, too
\end{mylang}
\end{document}
我的问题是是否有可能：
Only a test, this is not a comment
XYZ this should colored as a comment
and this line too
this is not a command, because only lines starting with XYZ
are comments
This is not a comment, too
包含在一个文件中，然后将此文件加载到主 tex 文件中，然后获得与文本包含在上述 tex 文件中时相同的颜色。我尝试了以下方法，但没有奏效：
\documentclass{report}
\usepackage{listings,xcolor}
{\catcode`\^^M=12 \def\marshal{\lstdefinelanguage{text}{comment=[s]{^^MXYZ}{^^M^^M}}}\expandafter}\marshal
\begin{document}
\lstinputlisting[language=text]{input.text}
\end{document}
其中input.text包含代码：
Only a test, this is not a comment
XYZ this should colored as a comment
and this line too
this is not a command, because only lines starting with XYZ
are comments
This is not a comment, too
谢谢
