XML Processing

[Alexandre Enkerli <aenkerli@indiana.edu>]

Hello all,
I'm building an exam using "ExamView Pro" which has, surprisingly, an 
XML export feature. I'd like to process the exam content into ConTeXt. 
I've looked at the "Example" file and tried to understand how it all 
works, but I'm not sure I can. So far, I've been able to process 
entities and MathML using the mm* and ent as options for --xmlfilter 
(texexec --pdf --xmlfilter=mml,mmp,mmc,ent file.xml) but I can't even 
get <b> to work as planned with any of the xtag-* files. I'm guessing I 
need to use the x-contml.tex file, but I don't know why.
Then, I'll probably need some guidance to have everything work.
The ExamView XML format uses attributes but I'd be happy with just 
getting the basic format straight.
What makes it somewhat harder is that I don't have so much experience 
with ConTeXt anyway.
So, I'd appreciate any help.

Here's the basic structure of the data I want to process:
	<question>
		<text></text>
		<choices>
			<choice></choice>
		</choices>
		<answer></answer>
		<info>
			<difficulty></difficulty>
			<reference></reference>
			<text-objective></text-objective>
		</info>
	</question>

In LaTeX terminology (sorry!) what I want is to have all the question 
texts as items in an "enumerate" and answer choices in an alphabetical 
enumerate for each question. Doesn't sound too hard. In fact, I guess I 
could probably do a find and replace...

Thanks in advance for your help.
