How to force line wrapping in listings package?

I have a problem concerning the listings package in latex. I need to embed a source code of the following XML document http://www.sparxsystems.com.au/downloads/profiles/EP_Extensions.xml in my master thesis' appendix. The problem is, no matter what options I pass to the package, I don't seem to be able to fit it on the page. The lines in the listing are too long, and the listings package doesn't wrap them, which seems odd... What combination of options will do the trick?

At the moment I use the following lstset instruction:

\lstset{
breakindent=0em,
language=XML,
basicstyle=\footnotesize,
numbers=left,
numberstyle=\footnotesize,
stepnumber=2,
numbersep=5pt,
backgroundcolor=\color{white},
showspaces=false,
showstringspaces=false,
showtabs=false,
frame=single,
tabsize=2,
captionpos=b,
breaklines=true,
breakatwhitespace=true,
breakautoindent=true,
escapeinside={\%*}{*)},
linewidth=\textwidth
}

Which, with no other options set, and combined with the following command:

\lstinputlisting{EP_Extensions.xml}

Lists the given file's source to the following output: alt text

latex

Not a great answer, but one idea is to word wrap the source code before including it. If you're on linux, the command fold can be used for this. Clearly this works best if the text is in a fixed width font, which i would recommend in any case for code listings.

A followup to Aaron's answer. I was using basicstyle=\ttfamily for my listings. I was therefore able to permit line breaking by changing

\usepackage[none]{hyphenat}

to

\usepackage[htt]{hyphenat}
%           ^^^

The hyphenat docs describe that the htt option "enables hyphenation of ... text typeset via either \texttt or \ttfamily." In my use case, I didn't see any hyphenation in my listings, but I did get the breaking.
