Remove the dot after section number in ToC [without any package]

Question

I'm using the book class and I want to remove the final dot in the section number, i.e, I have

1. Chapter Name
1.1. Section Name
1.1.1. Subsection Name
1.1.1.1. Subsubsection Name

I want

 1. Chapter Name
 1.1 Section Name
 1.1.1 Subsection Name
 1.1.1.1 Subsubsection Name

Looking for similar post, I found [How remove dot after section number in ToC with babel's spanish? and although the solution is very good I still have a problem: when I use the code es-nosectiondot the dot of the chapter disappears in the ToC, same is for LoF and LoT, i.e, Figure 1 (Table 1) instead Figure 1. (Table 1.), so, following the post I use the code \def\numberline#1{\hb@xt@\@tempdima{#1\if&#1&\else.\fi\hfil}}, which is useful because it solves the previous problem, but now the dot of the section, subsection and subsubsection appears in the ToC, i.e,

1. Chapter Name
1.1. Section Name
1.1.1. Subsection Name
1.1.1.1. Subsubsection Name

This is my MWE:

\documentclass{book}

\usepackage[spanish,es-nosectiondot]{babel}

\setcounter{secnumdepth}{3}
\setcounter{tocdepth}{3}
\counterwithout{figure}{chapter}
\counterwithout{table}{chapter}
\addto\captionsspanish{%
    \renewcommand{\tablename}%
    {Tabla}%
}

\makeatletter
 %%add prefix Figura/Tabla in LoF/LoT
 \long\def\@caption#1[#2]#3{%
  \par
  \addcontentsline{\csname ext@#1\endcsname}{#1}%
    {\protect\numberline{\csname fnum@#1\endcsname}{\ignorespaces #2}}%
  \begingroup
    \@parboxrestore
    \if@minipage
      \@setminipage
    \fi
    \normalsize
    \@makecaption{\csname fnum@#1\endcsname}{\ignorespaces #3}\par
  \endgroup}
  \renewcommand*\l@figure{\@dottedtocline{1}{0em}{5em}}%
  \let\l@table\l@figure
  %%egreg's code
 \def\numberline#1{\hb@xt@\@tempdima{#1\if&#1&\else.\fi\hfil}}
\makeatother

Answer 1

(I rewrote this answer from scratch after gaining a better understanding of the OP's formatting objectives.

I can't provide an answer that doesn't rely on external LaTeX packages. However, since the caption and tocloft packages have been around quite a few years, are very well debugged, and are known to work well with the book document class, I'm not going to make any apologies for employing these two packages.

I suggest you (a) keep using the instruction \usepackage[spanish,es-nosectiondot]{babel}, (b) employ the caption to change the label separator from : ("colon") to . (period) in the body of the document, and (c) employ the tocloft package to modify the appearance of figure and table entries in the LoF and LoT, respectively. You can ditch the code chunk between \makeatletter and \makeatother in your MWE, though.

\documentclass{book}
\usepackage[spanish,es-nosectiondot]{babel}
\addto\captionsspanish{%
   \renewcommand{\tablename}{Tabla}
   \renewcommand{\listtablename}{\'Indice de tablas} % do you need this?
}

\setcounter{secnumdepth}{3}
\setcounter{tocdepth}{3}
\counterwithout{figure}{chapter}
\counterwithout{table}{chapter}

%% modify the separator between caption numbers and text
\usepackage{caption}
\captionsetup{labelsep=period,skip=0.333\baselineskip}

\usepackage[titles]{tocloft}
%% modify appearance of entries in LoF and LoT
\cftsetindents{figure}{0em}{5em} % how much space to set aside
\cftsetindents{table}{0em}{5em}
\renewcommand{\cftfigpresnum}{\figurename\space} % prefix material
\renewcommand{\cftfigaftersnum}{.}               % postfix material
\renewcommand{\cfttabpresnum}{\tablename\space}
\renewcommand{\cfttabaftersnum}{.}

\begin{document}

\tableofcontents
\listoffigures
\listoftables

\chapter{Chapter}
\section{Section}
\begin{table}[h] \caption{Some table} \centering abc \end{table}
\begin{figure}[h] \caption{A figure} \centering xyz \end{figure}
\subsection{Subsection}
\subsubsection{Subsubsection}
\end{document}

Answer 2

Is this different from what you want?

\documentclass{book}
\usepackage[spanish]{babel}

\usepackage{titlesec}
\titlelabel{\thetitle\quad}

\begin{document}

\chapter{Test}
\section{Test}
\subsection{Test}

\end{document}
