 Hi Josh, I had fun figuring this one out. I'm not very good at this grouping stuff but it DOES produce the desired output (and an instructor once told me that getting the proper results is 70% of the grade). The only problem I can see with my solution is that there MUST always be the same limits for every premium within a class. So if a premium does not have the same limit attribute as the others within the class then this will not work. In the time I have for this I couldn't figure out how to group columns by limit (think pivot table). Also, I am using the for-each-group instruction which is an XSLT version 2 syntax. I'm not smart enough to understand Muenchian grouping but if you are restricted to version 1, then you should be able to figure out a way to emulate the version 1 grouping based on my version 2 example here. Just FYI, if I had to do this I would massage the data into a more XSL-friendly format before trying to output it for display. I would use a <xsl:variable> at the top of the document and reorganize the data so that I looks more like the format in your question and then use basic templates on that new structure. <ratePremiums> <class id="1"> <driving_record value="0"> <limit value="200"> <premium>820.7014415999998</premium> </limit> <limit value="300"> <premium>853.5294992639998</premium> </limit> </driving_record> ... </class> ... </ratePremiums> Good luck ;-) --Jim Neff <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" > <xsl:output method="html" indent="yes"/> <xsl:template match="ratePremiums"> <html> <body> <xsl:apply-templates select="coverage" /> </body> </html> </xsl:template> <xsl:template match="coverage"> <xsl:for-each-group select="premium" group-by="@class" > <p> class = <xsl:value-of select="current-grouping-key()" /> </p> <table> <tr> <th> <!-- first one is blank --> </th> <xsl:for-each-group select="current-group()" group-by="@limit"> <th> <xsl:value-of select="current-grouping-key()" /> </th> </xsl:for-each-group> </tr> <xsl:for-each-group select="current-group()" group-by="@drivingRecord"> <tr> <td> <xsl:text>DR = </xsl:text> <xsl:value-of select="@drivingRecord" /> </td> <xsl:for-each select="current-group()"> <td> <xsl:value-of select="." /> </td> </xsl:for-each> </tr> </xsl:for-each-group> </table> </xsl:for-each-group> </xsl:template> </xsl:stylesheet> > -----Original Message----- > From: cknell@xxxxxxxxxx [mailto:cknell@xxxxxxxxxx] > Sent: Tuesday, March 01, 2005 8:50 AM > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: RE: Grouping by attribute values > > Go to this URL > (http://techrepublic.com.com/5046-22-0.html?SearchThis=Muenchi > an+grouping&nodeIds=all&go=GO) and get this document: - > Overcoming decades old legacy systems with XSLT and Muenchian > grouping . > -- > Charles Knell > cknell@xxxxxxxxxx - email > > > > -----Original Message----- > From: Josh Taylor <jktylr@xxxxxxxxxxx> > Sent: Tue, 01 Mar 2005 09:38:16 -0400 > To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx > Subject: Grouping by attribute values > > I have the following problem.
