I need to convert an exam written in ConTeXt to an ascii text file like

with ConTeXt itself.
Can you show a small example of the corresponding tex source?

If you are willing to add more markup, then TeX can do the parsing for
you.

You can create a mode for ascii output that redefines all the environments
to *typeset* the correct output, which you can then convert to text using
pdftotext.
Another option is to write everything in XML (it is almost the same ...)
<question title="...", points=...., difficulty=...>
<text> A ruby .. </text>
<options>
<option> ... </option>
<option> ... </option>
<option correct="yes"> ... </option>
<option> ... </option>
</option>
<hint>

</question>
With a few setup commands, ConTeXt can directly typeset an xml file.
Parsing the xml file to generate ascii text can be done using your
favourite programming language (or using ConTeXt by typesetting the
desired output and using pdftotext).
And the desired output is...

Maybe a regexp would do, followed by a bit of hand editing, but if there
is a way of doing this in ConTeXt that would be very convenient.
If this is something that you need to do only a few types, anything quick
and dirty will suffice. But for the long run it makes sense to have a more
detailed markup and then you do not need to worry about the correctness of
the conversion.
