Yes you can, but of course you need a dedicated processor. XML is just a
syntax :-) One thing you could use for this is XSP, available as part of
AxKit (it's useful enough that I'd like to see it split out, but it looks
like no one has the time to work on that right now).
I don't know of anyone that's defined a control structures taglib, but of
course you can always use XSP Core to do that. In fact it is rarely needed as
in the general case for example for loops, you'd simply output what it is you
want to loop over as the output of XSP, and then XSLT will take care of
converting that to whatever output you want, most of the time taking care of
the looping transparently (at whatever degree of depth and/or recursivity).

If you are considering switching to XML (even if it is in a very distant
future) then I'd recommend still using valid XML rather than an XML-like
syntax. It may be useless now, but if you're thinking of changing it'll make
the change trivial.

There's AxKit, and I think that other packages can do that too
(Apache::PageKit ?).

By the parser itself, no, its job is simply to parse, nothing more. You could
however rather trivially create a SAX processor, and XSP taglib, etc that
would do that job.
