General ⇒ Is it possible to use \ref to refer other documents?

[jazzgossen]

I have two documents, and if possible I'd like to refer to a section or algorithm label in one document from the other.

Is this possible?

So document one might be

Code: Select all

\documentclass{article}

\begin{document}

\section{introduction}
\label{sec:intro}

\end{document}

and document two would be something like

Code: Select all

\documentclass{article}

\begin{document}

\section{introduction}
Refer to Section~\ref{sec:intro} in the other document.

\end{document}

Add in the Preamble of the second document:

Code: Select all

\usepackage{xr}
\externaldocument{first_document_name}

Infos about xr package can be found here.
