for the question in Moodle's XML standard 2.3.
exams2moodle will produce a XML file that may be uploaded in Moodle. It proceeds by (1)
calling Sweave on each exercise, (2) reading the resulting LaTeX code, (3)
transforming the LaTeX code to HTML, and (4) embedding the HTML code in a XML file using the
Moodle 2.3 standards for exams/quizzes. For steps (1) and (2) the standard drivers in xexams are used. In step (3), a suitable
transformation function is set up on the fly using make_exercise_transform_html, see also
the details section in exams2html.
For step (4), the function will cycle through all questions and exams to generate the final XML
file in Moodle 2.3 standard. The structure of the resulting XML file is such that one category
will be set for the exam/quiz using the exam/quiz name (or this category may be
suppressed (i.e., not included in the XML) by setting iname = FALSE), followed by one
category/section for each question, while the replicates of each question will be included in the
corresponding category/section. Note that category/section names may also be provided in the
\exsection{} tag in the .Rnw files, or within argument stitle in
exams2moodle. This may be useful when questions should automatically be added to already
existing Moodle question banks. (See also the argument descriptions above)
The XML code for each question is then generated using function make_question_moodle23.
Note that for each question type, either the arguments of make_question_moodle23 may be set
within num, mchoice, schoice, string and cloze in
exams2moodle, by providing a named list of specifications that should be used, or for each
questiontype, a function that produces the question XML code may be provided to num,
mchoice, schoice, string and cloze. E.g., to suppress the solution
for numeric questions one may set num = list(solution = FALSE).
