Subject: Removing duplicates - grouping problem From: Rebecca Crisafulli <crisa@xxxxxxxxxxx> Date: Wed, 18 Oct 2000 13:42:49 -0400 (EDT) |
I am new to XSLT. I have looked for the answer but no luck I am trying to group, sort and remove duplicates. I can achieve the first two, but can not remove duplicates. For each term (see XML file), I want to group, sort and remove dups from the <sab>s (the term's source). I have tried variations of the Stylesheet with no luck. The present stylesheet gives me grouped and sorted. Help get rid of the duplicates. Hopefully this is a easy one for the pros on this mailing-list. Why does the 'not condition' in my select not take care of the duplicates. Run from command line -- java com.jclark.xsl.sax.Driver Thanks --Rebecca XML file ----- <?xml version="1.0"?> <UMLSCollection> <MetaGroup> <concept> <cn>Zygoma</cn> <term> <tn>Cheek Bone</tn> <termVariant> <str>Cheek Bone</str> <strSource> <sab>MSH2000</sab> </strSource> </termVariant> <termVariant> <str>Cheek Bones</str> <strSource> <sab>MSH2000</sab> </strSource> </termVariant> <termVariant> <str>Cheek-bone</str> <strSource> <sab>S0475897</sab> </strSource> <strSource> <sab>MSH2000</sab> </strSource> </termVariant> </term> <term> <tn>Jugal Bone</tn> <termVariant> <str>Jugal Bone</str> <strSource> <sab>MSH2000</sab> </strSource> </termVariant> </term> </concept> </MetaGroup> </UMLSCollection> ---- Stylesheet <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format"> <xsl:template match="UMLSCollection"> <html> <xsl:apply-templates/> </html> </xsl:template> <xsl:template match="concept"> Concept Name: <xsl:value-of select="cn"/><br/> <xsl:apply-templates select="term"/> </xsl:template> <xsl:template match="term"> <xsl:text> Synonym: </xsl:text> <xsl:value-of select="tn"/><br/> Source: <br/> <xsl:for-each select="termVariant/strSource/sab[not(.=preceding-sibling::termVariant/st rSource/sab)]"> <xsl:sort select="."/> <xsl:value-of select="."/><br/> </xsl:for-each> </xsl:template> Rebecca A.
