varias tablas de contenido

Question

¿Cómo se debe editar el código si se incluye un archivo tex externo (a través de \input)? El archivo externo debe tener su propia tabla de contenidos independiente.

    \documentclass[a4paper]{article}
    % renew \contentsline for toc to include hypertarget
    \let\oldcontentsline\contentsline%
    \renewcommand\contentsline[4]{%
    \hypertarget{toc#4}{}%
    \oldcontentsline{#1}{#2}{#3}{#4}}

    % renew \section to link to the toc
    \titleformat{\section}
    {\normalfont\Large\bf}
    {{\thesection} \hyperlink{tocsection.\thesection}{#1}}
    {1pc}
    {}

    % renew \subsection to link to the toc
    \titleformat{\subsection}
    {\normalfont\bf}
    {{\thesection} \hyperlink{tocsubsection.                    \thesubsection}{#1}}
    {1pc}{}

    % renew \subsubsection to link to the toc
    \titleformat{\subsubsection}
    {\normalfont\bf}
    {{\thesection} \hyperlink{tocsubsubsection.        \thesubsubsection}{#1}}
    {1pc}{}

    \begin{document}
    \tableofcontents


    \section{abcd}


    \end{document}

¡Gracias por la ayuda!
