I have a collection of publications records in XML that store Discipline,
Title, Date, and other characteristics, including a flag indicating whether
the publication should show up on a Highlights page. I now want to output
the Highlights page, and I want the value of Discipline to be output only
once per group of records sharing that discipline. E.g.
That's a grouping problem. Look into the XSL FAQ for "grouping", or at http://www.jenitennison.com/xslt/grouping/index.html
Your groups are keyed by the Disciplines element. Think of it as the following pseudo code: select first members of all groups output Discipline select all members of current group Output values of Title, Publisher, and Date
Some XSLT to get you started <xsl:key name="r-d" match="Record" use="Disciples"/> <xsl:template match="InstCorr"> <xsl:for-each select="Record[ generate-id()=generate-id(key('r-d',Disciples)]"> <xsl:value-of select="Disciples"/> <xsl:for-each select="key('r-d',Disciples)"> <xsl:value-of select="Title"/> ... </xsl:for-each> </xsl:for-each> </xsl:template> (Beware: untested)
