Displaying two XML listings side by side.

Question

I have two XML outputs from a program that I would like to include in a LaTeX document. I would like them to appear side-by-side each in its own box. So that a reader can compare the two outputs while reading the document. Can't seem to find a way to do this, without making images for each output and adding both as images/graphics. Could there be a better option?

Answer 1

You need to use some verbatim environment or macro to display source code. The listings package is good for this and provides syntax highlighting, but unfortunately not for XML.

You should place each code then into a minipage environment with a width slightly smaller than .5\textwidth. Something along:

\begin{center}
\begin{minipage}{.48\textwidth}
  \lstinputlisting[breaklines]{file1.xml}
\end{minipage}
\hfill
\begin{minipage}{.48\textwidth}
  \lstinputlisting[breaklines]{file1.xml}
\end{minipage}
\end{center}

The exact code depends if you need it as a floating environment, need captions etc.
