When using Elsevier's article template elsarticle, the references to appendix sections return Appendix X instead of X. I personally dislike the double space, so I was trying to create a macro to retrieve the X from the reference. I tried to follow this answer guidance to create such a macro using xstring's \StrRight, which allows the retrieval of the last character of a given string. However, I cannot understand the result I am obtaining. Below, I present a minimal code to reproduce the problem and also a screenshot of its result.

\documentclass{elsarticle}

\usepackage{xstring}
\newcommand{\getLastLetter}[1]{%
    \StrRight{#1}{1}[\lastLetter]%
    \lastLetter
}


\begin{document}


The label letter of \ref{appendixSectionLabel} is \getLastLetter{\ref{appendixSectionLabel}}.


\appendix
\section{}
\label{appendixSectionLabel}


\end{document}

  • elsarticle.cls defines \appendixname with \def\appendixname{Appendix } (with the space). I can't be sure, but this sounds like a typo to me. You can try \renewcommand\appendixname{Appendix} and observe for side effects... – gusbrs Jan 30 '24 at 02:02
  • @gusbrs Your workaround was good enough to solve my root problem. Thank you. – FxMySz Jan 30 '24 at 02:27
