A quine must also not process any input.

You XML-producing program may be very useful, but it's not really a
quine, serious or otherwise.

That sounds as if the program reads input (but it's not explicitly
stated) as well as not producing the program text but some XML
representation of the program text.  That would make it not a quine for
two reasons.

How do you process a source tree in completely portable ANSI C?
