How would you do it in another language?

Are the "item-id" attributes always a single character in length?

Is there some maximum number of <answer> elements for all <question>s?
I.e. can the script assume that no <question> will ever have more than
5 <answer>s?  If so, you can precompute all possible permutations and
just use the elements of the precomputed permutation as indexes into
the <answer> elements for a given <question>.
