C++ and XML...

[Kit Plummer]

The basic XML structure would look something like the following:

<xml file>
----------

<?xml version="1.0"?>
	<!-- preflight checklist prompts -->
	<preflight>
		<prompt>
			<question>Aircraft Documents?</question>	
			<answer>Check</answer>
		</prompt>
		<prompt>
			<question>Battery On?</question>
			<answer>Check</answer>
		</prompt>
		<prompt>
			<question>Flaps Down?</question>
			<answer>Check</answer>
		</prompt>
	</preflight>

----------
<xml file>

Granted this is an extremely stripped down checklist, but it would do in
the scheme of prototyping.  Also, there would be another root structure
for other checklists like emergency.

The menu structure to get to the various checklists would be hardcoded
rather than pulled from a file because it would be the same regardless
of aircraft.

Anyway, what I think is to happen is:

- The app is in a wait state, prompting for checklist name (preflight).

- Once (preflight) is entered, the checklist is parsed and then cycled
sequentially until the hash is complete.  NOTE: Future consideration
will need to be given to the fact that it is possible for a negative
answer.  In that case the given point in the checklist will need to be
marked in memory.  I haven't thought about this much...

I am working on a formal DTD and XML files for each checklist.  I should
be able to finalize something within the next couple of days. (I have to
teach class today and tomorrow.)
