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, prakash Ragulf Pickaxe <ragulf.pickaxe@ To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx gmail.com> cc: (bcc: omprakash.v/Polaris) Subject: Re: [xsl] Grouping 12/07/2005 03:28 PM Please respond to xsl-list Hi again, > I take back my previous post as I don't see where I am wrong. > The muenchian grouping is not required for the answers and only for the > questions that too only if the OP is prticular about it. > > Otherwise, my code should work fine. 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.
