Beautifying XML w/ XSL

In the spirit of not re-inventing the wheel, I imagine that some people out there have already built some XSL stylesheets to help beautify XML code.

If anyone knows where I can find something like this, I would greatly appreciate any help in finding it.

Of course, I would probably be just as happy with any scripted (perl,js,vbs) app that does the same in a windows environment(MSXML is installed). 

Free, is my preference, of course.
