PDF::Template and Excel::Template, combined with XML::Parser (which they already use cause the layout/template files are in XML) and some code anyone can write should be able to do this. I didn't extend the param() method for those modules beyond what HTML::Template's does because that wasn't in my initial scope. But, there's no reason I couldn't accept an XML document (either filename, filehandle, or scalarref) as the parameter list ... unless I'm missing something obvious (which is always a distinct possibility).
