AvalonEdit XML Pretty Print

Question

I am using Avalon Editor in my project to display existing XML (read only) I would like to show it with the elements in separate lines and neatly indented, regardless of the formatting of the source XML. Example:

<City Name="Paris"><Street Name="Rue du hoquet">My House</Street></City>

shall be shown as:

<City Name="Paris">
    <Street Name="Rue du hoquet">
        My House
    </Street>
</City>

I know that there are many examples using .Net, but instead of reading and re-writing the XML before sending it to Avalon, it would be nicer if Avalon cound do the job by itself. I tried working with folding, but I suspect that folding requires separate lines to work with. Since I am using Avalon for displaying XML only, racting on the user's editing is not an issue.
