比較兩位 natbib 參考文獻的作者

Question

我試圖找出兩個參考文獻是否具有相同的作者natbib。但我似乎無法進行基本的字串比較。由於沒有更深入的了解，我已經嘗試了我能找到的一切（，，，，xstring... ）。沒有什麼真正有效。如果有人可以修復我的功能，我會很高興。\detokenize\expandafter\relaxTest

\documentclass{article}
\usepackage{natbib}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
    @article{ArticleX, author = "AuthorA", year = "2000"}
    @article{ArticleY, author = "AuthorA", year = "2010"}
    @article{ArticleZ, author = "AuthorB", year = "2010"}
\end{filecontents}
\newcommand{\Test}[2]{
    \ifx\citeauthor{#1}\citeauthor{#2}
        Yes!
    \else
        No!
    \fi
}
\begin{document}
    Oh, \cite{ArticleX} and \cite{ArticleZ} don't have the same author? \Test{ArticleX}{ArticleZ} Ok!

    But \cite{ArticleX} and \cite{ArticleY} surely have! \Test{ArticleX}{ArticleY} No, either??

    \bibliographystyle{unsrtnat}
    \bibliography{\jobname}
\end{document}

Answer 1

這有效：

% https://tex.stackexchange.com/questions/8981/
\newcommand{\ignoreoutput}[1]{\setbox0\vbox{\everypar{}#1}}
\makeatletter
\newcommand{\Test}[2]{
    \ignoreoutput{\citeauthor{#1}}
    \edef\NumberOne{\NAT@name}
    \ignoreoutput{\citeauthor{#2}}
    \edef\NumberTwo{\NAT@name}
    \ifx\NumberOne\NumberTwo
        Yes!
    \else
        No!
    \fi
}

我仍然歡迎更優雅的答案，但這解決了我的問題。
