Hi all

I've the following xml doc:

<recordset>
     <row>
        <question_id>1</question_id>
        <answer>blah blah blah...</answer>
     </row>
     <row>
        <question_id>1</question_id>
        <answer>blah blah blah...</answer>
     </row>
     <row>
        <question_id>2</question_id>
        <answer>blah blah blah...</answer>
     </row>
     <row>
        <question_id>2</question_id>
        <answer>blah blah blah...</answer>
     </row>
     ...etc...
</recordset>

I'd like to be able to group the output so I get the following:

Answers to question 1:
     - blah blah blah...
     - blah blah blah...
Answers to question 2:
     - blah blah blah...
     - blah blah blah...
...etc...

There isn't a fixed number of answers to each question, so grouping on a
set of say 10 isn't possible. I've tried using preceeding-sibling, but
can't seem to get anywhere with it.

Any ideas?
