No utilizar bibliografía en otro archivo tex

Question

Tengo dos archivos .tex: reftest.tex que contiene los detalles principales: referencia, figura, ecuación; y cross_ref.tex. En cross_ref.tex, quiero hacer una referencia cruzada de la cita de referencia en el archivo reftest.tex. Sin embargo, no se pudo citar. ¿Podrías ayudarme a solucionarlo? este es mi codigo

En reftest.tex:

 \documentclass[preprint,12pt, sort&compress]{elsarticle}
\def\bibsection{\section*{References}}
\usepackage[draft]{hyperref}
\usepackage{graphicx}
\usepackage{caption,subfig}
\usepackage{amssymb}
\usepackage{amsmath}

\begin{document}
This is ref \cite{S_Goossens}

\begin{figure} 
  \centering \includegraphics[width=0.5\linewidth]{example-image-a}
  \caption{This is caption}
  \label{fig:2}
\end{figure}

\begin{equation}
\label{eq:1} 
  y=x
\end{equation}

\begin{thebibliography}{00}

%% Text of bibliographic item
\bibitem{S_Goossens}SMichel Goossens, Frank Mittelbach, and Alexander Samarin Addison-Wesley, Reading, Massachusetts, 1993.

\end{thebibliography}
\end{document}

En cross_ref.tex

\documentclass[preprint,12pt, sort&compress]{elsarticle}
\def\bibsection{\section*{References}}
\usepackage[draft]{hyperref}
\usepackage{graphicx}
\usepackage{caption,subfig}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{xr}
\externaldocument{reftest}

\begin{document}
This is ref \cite{S_Goossens} in the reftest file

Figure \ref{fig:1} is figure in the reftest file

The  Eq. \eqref{eq:1} is a equation 

\end{document}

Mi salida no puede mostrar el número de cita en el archivo cross_ref.tex

Answer 1

Con xciteél parece estar funcionando. Tenga en cuenta xr-hyperen lugar de `xr y el orden de carga del paquete.

reftest.tex

\documentclass[preprint,12pt, sort&compress]{elsarticle}
\def\bibsection{\section*{References}}
\usepackage{graphicx}
\usepackage{caption,subfig}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage[draft]{hyperref}

\begin{document}
This is ref \cite{S_Goossens}

\begin{figure} 
  \centering \includegraphics[width=0.5\linewidth]{example-image-a}
  \caption{This is caption}
  \label{fig:1}
\end{figure}

\begin{equation}
\label{eq:1} 
  y=x
\end{equation}

\begin{thebibliography}{00}

%% Text of bibliographic item
\bibitem{S_Goossens} Michel Goossens, Frank Mittelbach, and Alexander Samarin 
Addison-Wesley, Reading, Massachusetts, 1993.

\end{thebibliography}
\end{document}

crossref.tex

\documentclass[preprint,12pt, sort&compress]{elsarticle}
\def\bibsection{\section*{References}}
\usepackage{graphicx}
\usepackage{caption,subfig}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{xcite}
\usepackage{xr-hyper}
\usepackage[draft]{hyperref}
\externaldocument{reftest}
\externalcitedocument{reftest}

\begin{document}
This is ref \cite{S_Goossens} in the reftest file

Figure \ref{fig:1} is figure in the reftest file

The  Eq. \eqref{eq:1} is a equation 

\end{document}

Salida decrossref.tex

Answer 2

Bien, aquí tienes una solución.

Si utiliza un archivo bibliográfico externo (literatur.bib):

    @BOOK{S_Goossens,
  title = {Some title},
  publisher = {Addison-Wesley},
  year = {1993},
  author = {Goossens, S. Michel and Mittelbach, Frank and Samarin, Alexander},
  address = {Reading, Massachusetts},
  owner = {polz},
  timestamp = {2016.03.24}
}

Sólo necesitas cambiar tu reftest.tex para usar la bibliografía externa en lugar de usar el thebibliographyentorno:

\documentclass[preprint,12pt, sort&compress]{elsarticle}
\def\bibsection{\section*{References}}
\usepackage[draft]{hyperref}
\usepackage{graphicx}
\usepackage{caption,subfig}
\usepackage{amssymb}
\usepackage{amsmath}

\begin{document}
This is ref \cite{S_Goossens}

\begin{figure} 
  \centering \includegraphics[width=0.5\linewidth]{example-image-a}
  \caption{This is caption}
  \label{fig:1}
\end{figure}

\begin{equation}
\label{eq:1} 
  y=x
\end{equation}

\bibliography{literatur}{}
\bibliographystyle{plain}

\end{document}

Si ahora incluye el \usepackage{bibentry}comando en el preámbulo de su cross_rex.tex e incluye literatur.bib vía \nobibliography{literatur}{}, lo que evita imprimir la bibliografía, entonces funciona de la manera que desea.

\documentclass[preprint,12pt, sort&compress]{elsarticle}
\def\bibsection{\section*{References}}
\usepackage[draft]{hyperref}
\usepackage{graphicx}
\usepackage{caption,subfig}
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{xr}
\externaldocument{reftest}

\usepackage{bibentry}

\begin{document}
This is ref \cite{S_Goossens} in the reftest file

Figure \ref{fig:1} is figure in the reftest file

The  Eq. \eqref{eq:1} is a equation 

\nobibliography{literatur}{}

\end{document}
