Subject: RE: [xsl] Complex grouping problem, please help. From: kakridge@xxxxxxxxxxxxx Date: Sat, 10 Jan 2004 21:32:47 -0500 |
The approach I am taking with this has been to for-each the first occurrence of every tutor in Grade node. I then for-each a key matching all Students to based on each tutor. I keep trying to only limit the key to the current grade, but I don't think it is working. <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> What am I missing? The key doesn't seem to only return students in the given grade. It returns all students in all grades for the tutor. --- kakridge@xxxxxxxxxxxxx wrote: > I have been having a problem with grouping.
