我尝试使用以下最小示例测试包catchfilebetweentags，但出现编译错误。这里出了什么问题？如何修复？
内容catch_main.tex
\documentclass{article}%
\usepackage{catchfilebetweentags}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\CatchFBT@Fin@l}{\endlinechar\m@ne}{}
{}{\typeout{Unsuccessful patch!}}
\makeatother
\begin{document}
\ExecuteMetaData[inputfile]{mytag1}
\ExecuteMetaData[inputfile]{mytag1}
\ExecuteMetaData[inputfile]{mytag2}
\end{document}
内容inputfile.tex
\documentclass{article}%
\begin{document}
Some text.
%<*mytag1>
This is the text for mytag1.
% </mytag1>
%<*mytag2>
This is the other text for mytag2.
% </mytag2>
\end{document}

存在语法错误inputfile.tex。结束标记不应包含空格：
% </mytag1>⇒%</mytag1>
修正版本inputfile.tex：
\documentclass{article}%
\begin{document}
Some text.
%<*mytag1>
This is the text for mytag1.
%</mytag1>
%<*mytag2>
This is the other text for mytag2.
%</mytag2>
\end{document}
