Re: Grouping

Hi,

"<xsl:value-of select="key('rec', question_id)/answer"/>
not give only the first row/answer element with a given question_id,
no matter the current row element?"

Yes. Looks like Iam missing an xpath index in my expression. something like
the following and I would have been right ofcourse.

<xsl:value-of select="key('rec', question_id)[x]/answer"/>

where x is the current row in question(no pun intended).

But ofcourse that would mean having a recursive template to keep track of
the current row etc. which makes a solution using key less preferable in
this case I think.

Thanks for pointing out my error.

cheers,

Hi again,

Yes, your solution would work fine on the input given by the OP (is OP
for Original Poster?). My point was that if the question_id's where
not ordered, then I think that your answer would not work, for
example:

<recordset>
    <row>
       <question_id>1</question_id>
       <answer>1: blah blah blah...</answer>
    </row>
    <row>
       <question_id>2</question_id>
       <answer>2: blah blah blah...</answer>
    </row>
    <row>
       <question_id>1</question_id>
       <answer>3: blah blah blah...</answer>
    </row>
    <row>
       <question_id>2</question_id>
       <answer>4: blah blah blah...</answer>
    </row>
    ...etc...
</recordset>

And now that I think about it, would:
<xsl:value-of select="key('rec', question_id)/answer"/>
not give only the first row/answer element with a given question_id,
no matter the current row element?

As I said, if I am wrong in my assumptions on how the language work, I
would be grateful for clarification.
