But this means that the whatever.tex file needs to exist beforehand and the result is whatever.pdf

I want the actual PDF to be produced have a name that comes from the XML I am processing and thus the whatever.tex file be created by lua. There is no whatever.tex file before I run the command.

Pre-command:
	XML:
		contains file name “foo”
	there is no .tex file

Command:
	produces foo.tex (gets the name from the XML) and “foo.pdf"
