如何删除孩子的分支

我使用 tikz 中的 node/child 创建一棵树，如下所示。

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\tikzstyle{nodestyle} = [circle,draw,minimum size=5pt]

\node [nodestyle, inner sep=0pt] {$A|_{\aleph_0}$}
child {node {$\vdots$}
    child {node [nodestyle, inner sep=4pt] (b1) {$S$}
        child {node [nodestyle,inner sep=0pt] {$\{X_1\}$}
            child {node [nodestyle, inner sep=1pt] {$X_1$}}}
        child {node [nodestyle,inner sep=1pt] (e) {$X_2$}}}
}
child {node {$\vdots$}
child {node [nodestyle, inner sep=2pt] (b3) {$X_1$}}}
child {node {$\cdots\cdots$}}
child {node {$\vdots$}
child {node [nodestyle, inner sep=2pt] (an) {$X_n$}}
}; 
\end{tikzpicture}
\end{document}

现在我想删除 child 中 \cdots 上方的分支。我该怎么做？谢谢。

我相信你会找到更好的解决方案（等待其他答案），但这里有一个快速破解：

\documentclass{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
%\tikzstyle{nodestyle} = [circle,draw,minimum size=5pt] REPLACED WITH CODE BELOW AFTER @cfr's COMMENT
\tikzset{nodestyle/.style={circle,draw,minimum size=5pt}}
\node [nodestyle, inner sep=0pt] {$A|_{\aleph_0}$}
child {node {$\vdots$}
    child {node [nodestyle, inner sep=4pt] (b1) {$S$}
        child {node [nodestyle,inner sep=0pt] {$\{X_1\}$}
            child {node [nodestyle, inner sep=1pt] {$X_1$}}}
        child {node [nodestyle,inner sep=1pt] (e) {$X_2$}}}
}
child {node {$\vdots$}
child {node [nodestyle, inner sep=2pt] (b3) {$X_1$}}}
child[opacity=0] {node[opacity=1] {$\cdots\cdots$}}
child {node {$\vdots$}
child {node [nodestyle, inner sep=2pt] (an) {$X_n$}}
}; 
\end{tikzpicture}
\end{document}

输出：

在此处输入图片描述

我刚刚给子节点添加了零不透明度，并为其节点添加了一个不透明度

我也在这里找到了解决方案：tikz 树：如何不绘制单个边缘

\documentclass{standalone}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
%\tikzstyle{nodestyle} = [circle,draw,minimum size=5pt] REPLACED WITH CODE BELOW AFTER @cfr's COMMENT
\tikzset{nodestyle/.style={circle,draw,minimum size=5pt}}
\node [nodestyle, inner sep=0pt] {$A|_{\aleph_0}$}
child {node {$\vdots$}
    child {node [nodestyle, inner sep=4pt] (b1) {$S$}
        child {node [nodestyle,inner sep=0pt] {$\{X_1\}$}
            child {node [nodestyle, inner sep=1pt] {$X_1$}}}
        child {node [nodestyle,inner sep=1pt] (e) {$X_2$}}}
}
child {node {$\vdots$}
child {node [nodestyle, inner sep=2pt] (b3) {$X_1$}}}
child{node{$\cdots\cdots$} edge from parent[draw=none]}
child {node {$\vdots$}
child {node [nodestyle, inner sep=2pt] (an) {$X_n$}}
}; 
\end{tikzpicture}
\end{document}
