[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: Re:
The problem is that although it is grouped by grade, I need to group by grade and tutor. Here is the approach I have been trying: <xsl:key name="students-by-tutor" match="Grade/Students/Name" use="Tutor"/> <xsl:template match="School"> <xsl:for-each select="Grade"> <xsl:apply-templates select="."/> </xsl:for-each> </xsl:template> <xsl:template match="Grade"> <xsl:for-each select="Students/Student/Name[Tutor[not(. = preceding::Tutor)]]"> <xsl:sort select="Tutor"/> <xsl:variable name="gradeName" select="ancestor::Grade/Name"/> <xsl:for-each select=key('students-by-tutor ', Tutor)[ancestor::Grade/Name = $gradeName]> <xsl:apply-templates select="."/> </xsl:for-each> </xsl:for each> </xsl:template> This is a condensed version, but it is the gist of what I have been trying to do. I am not looking for anyone to do this for me... I just don't understand some of the grouping methods. I have read a few of the faq's and helpful sites, but do not see anything that applies like this. Maybe I am overcomplicating it though. -----Original Message----- From: owner-xsl-list@xxxxxxxxxxxxxxxxxxxxxx [mailto:owner-xsl-list@xxxxxxxxxxxxxxxxxxxxxx] On Behalf Of Wendell Piez Sent: Friday, January 09, 2004 6:58 PM To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: Re: Hi, At 06:17 PM 1/9/2004, you wrote: >I have been having a problem with grouping.

They are already grouped by grade, so it appears you just need to group students by tutors. Grouping in XSLT 1.0, while it is not trivial, is well-documented (in part because it's not trivial), and you will find a wealth of resources on line explaining various techniques of doing it, including both on the XSL FAQ (http://www.dpawson.co.uk/xsl/sect2/sect21.html) and everyone's favorite helper site for XSLT grouping, http://www.jenitennison.com/xslt/grouping/index.html. Since you haven't said exactly what's got you stuck here, it's impossible to offer more specific advice, short of simply writing the code to do this. And that really wouldn't be much help, would it? While the list has an interest in helping and encouraging you to learn XSLT, we don't have much interest in doing the job for you.... If you have a more specific or focused question on a point you find confusing, please don't hesitate to ask. (Oh, and use a subject line next time too. :-) Cheers, Wendell ====================================================================== Wendell Piez mailto:wapiez@xxxxxxxxxxxxxxxx Mulberry Technologies, Inc. http://www.mulberrytech.com 17 West Jefferson Street Direct Phone: 301/315-9635 Suite 207 Phone: 301/315-9631 Rockville, MD 20850 Fax: 301/315-8285 ---------------------------------------------------------------------- Mulberry Technologies: A Consultancy Specializing in SGML and XML ====================================================================== XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
