如何在 TikZ 多部分形状中使用数字到文本的转换函数

Question

我想使用foreach构造在多部分节点之间画线。但我发现问题是多部分anchors是用文本名称声明的：one, two, ...而不是数字。

我尝试使用fmtcount或numname包中的转换函数，但尽管它们在节点文本中有效，但我无法将其用作锚点引用。这可能吗？

\documentclass[tikz, border=1mm]{standalone}
\usetikzlibrary{shapes.multipart, positioning}
\usepackage{fmtcount}

\begin{document}
\begin{tikzpicture}[
    my shape/.style={
          rectangle split
        , rectangle split parts=#1
        , draw
        , anchor=center
        }
    ]
\node[my shape=3] (main){
    \numberstringnum{1} 
   \nodepart{two}
   \numberstringnum{2} 
   \nodepart{three}
   \numberstringnum{3}};

\node[my shape=3, right=2cm of main] (second)
{
    \numberstringnum{1} 
   \nodepart{two}
   \numberstringnum{2} 
   \nodepart{three}
   \numberstringnum{3}};    

\draw (main.one east) -- (second.two west);
%following lines fail.
%\draw (main.\numberstringnum{2} east) -- (second.\numberstringnum{3} west);
%\foreach \i in {1,...,3}
%   \draw (main.\numberstringnum{\i} east) -- (second.\numberstringnum{\i} west);
\end{tikzpicture}
\end{document}

宏可能不可扩展（我没有检查）但你基本上可以定义一个简单的开关，然后它就可以工作了

\documentclass[tikz, border=1mm]{standalone}
\usetikzlibrary{shapes.multipart, positioning}

\def\numname#1{%
  \ifcase#1zero\or one\or two\or three\or four\or five\or six\or seven\or eight\or nine\fi%
}

\begin{document}
\begin{tikzpicture}[
  my shape/.style={rectangle split, rectangle split parts=#1 , draw, anchor=center}]

\node[my shape=3] (main){\numname{1}\nodepart{two}\numname{2}\nodepart{three}\numname{3}};

\node[my shape=3, right=2cm of main] (second)
       {\numname{1}\nodepart{two}\numname{2}\nodepart{three}\numname{3}};

\draw (main.one east) -- (second.two west);
\draw (main.{\numname{2} east}) -- (second.\numname{3} west);
\foreach \i in {1,...,3}
   \draw (main.\numname{\i} east) -- (second.\numname{\i} west);
\end{tikzpicture}
\end{document}
