请问如何将附件pdf文件夹下的tikz代码添加到主文件里面，变成整个文档的边框，我尝试着导入pdf文件夹下的tex文件，但一直出现错误
我用的是texlive2020，XeLaTeX编译
插入页边框的代码我参考的这个https://tex.stackovernet.com/cn/q/20081网站的代码：这个网站的页边框示例代码如下：
\documentclass[10pt]{scrartcl}
\usepackage[margin=20mm,a6paper]{geometry}
\usepackage{tikz}
\usepackage{xifthen}
\usetikzlibrary{fit,calc}
\usepackage{lipsum}
\usepackage{everypage}
\parindent0mm
\newcommand{\currentsidemargin}{%
\ifodd\value{page}%
\oddsidemargin%
\else%
\evensidemargin%
\fi%
}
\AddEverypageHook{%
\ifthenelse{\isodd{\thepage}}
{ \begin{tikzpicture}[overlay, remember picture]
\path (current page.north west) ++(\hoffset, -\voffset) node[anchor=north west, shape=rectangle, inner sep=0, minimum width=\paperwidth, minimum height=\paperheight] (pagearea) {};
\path (pagearea.north west) ++(1in+\currentsidemargin,-1in-\topmargin-\headheight-\headsep) node[anchor=north west, shape=rectangle, inner sep=0, minimum width=\textwidth, minimum height=\textheight] (textarea) {};
\node[inner sep=0,fit=(pagearea.north east)(textarea.north east)(pagearea.south east)] (marginbox) {};
\draw (marginbox.south east) rectangle (marginbox.north west);
\draw (marginbox.south east) -- (marginbox.north west);
\end{tikzpicture}
}{}
}
\begin{document}
\lipsum[1-10]
\end{document}
