How to Draw xsd in Tikz

Question

How can I draw with xsd in TikZ?

Answer 1

Second attempt. You need to add some styles to simplify the code. A good way is to create new shapes but it's a long work. Here I saved some pictures with savedbox then you can reuse them inside new nodes but you need to take some precautions like inner xsep=0. A problem is to get the same height inside rectangle spli part. here i used \mystrutbut perhaps there is a batter method to do this.

\documentclass[11pt,landscape]{scrartcl}
\usepackage{tikz}
\usetikzlibrary{shapes.multipart} 

\def\vstrut{\vrule height 0.75ex depth 0.75ex width 0pt}
 \def\hstrut{\vrule height 0ex depth 0ex width 3mm}  
\begin{document}
\newsavebox{\figone}
\savebox{\figone}{%    
\begin{tikzpicture}
\fill (-2mm,-1mm) rectangle  (2mm,1mm); 
\fill[yshift=3mm] (-2mm,-1mm) rectangle  (2mm,1mm); 
\fill[yshift=-3mm ] (-2mm,-1mm) rectangle  (2mm,1mm);
\draw[thick] (-6mm,0) -- (-2mm,0)  (6mm,0) -- (2mm,0) ; 
\draw[thick]  (-2mm,-3mm) -- ++(-2mm,0) -- ++(0mm,6mm)--++(2mm,0);
\draw[thick]  (2mm,-3mm) -- ++(2mm,0) -- ++(0mm,6mm)--++(-2mm,0); 
\end{tikzpicture}%
}%

\newsavebox{\figtwo}
\savebox{\figtwo}{%    
\begin{tikzpicture}
\draw (0mm,-3mm)--++(0,6mm)--++(3mm,3mm)--++(15mm,0)--++(3mm,-3mm)--++(0,-6mm)--++(-3mm,-3mm)--++(-15mm,0)--cycle;
\end{tikzpicture}%
}   

\newsavebox{\tiret}
\savebox{\tiret}{%
\begin{tikzpicture}
\draw[thick] (-2mm,0mm)--++(4mm,0);
\end{tikzpicture}%
}% 

\newsavebox{\connect} 
\savebox{\connect}{%
\begin{tikzpicture}
  \node{\usebox\figone};
  \node[inner sep=0pt] (ft){\usebox\figtwo};
  \node[draw,minimum size=6mm,anchor=center,inner sep=0pt,fill=white,inner xsep=0](m) at (ft.east){};
  \node[inner sep=0pt] at (m) {\usebox\tiret};
\end{tikzpicture}%
}
\tikzset{split style/.style={rectangle split, rectangle split parts=2, draw,rectangle split part align={left}}}

 \tikzset{square/.style={draw,minimum size=6mm,anchor=center,inner xsep=0pt,fill=white}}
