Subject: removing duplicates problem From: Jeremy Quinn <jeremy@xxxxxxxxxxxxxxxxx> Date: Tue, 28 Dec 1999 20:29:53 +0000 |
I am in the situation of wanting to create a node-set of all the <person idref="Smith"/> and <author idref="Jones"/> tags with unique idref attributes. The tags can be found almost anywhere in the document. I am making a list of <person> and <author> elements using: <xsl:template name="people"> <xsl:variable name="all" select=".//person[@idref]|.//author[@idref]" /> then trying to remove duplicates by selecting into a new variable like this: <xsl:variable name="unique" select="$all[not(.=following::$all)]" /> before looking them up from another document and passing them to a "person" template: <xsl:for-each select="$unique"> <xsl:variable name="pid" select="(@idref)"/> <xsl:for-each select="document('../xml/data/people.xml')"> <xsl:apply-templates select="id($pid)"/> </xsl:for-each> </xsl:for-each> </xsl:template> The line trying to remove the duplicates does not compile, I guess I'm trying this the wrong way ;-) Any suggestions welcome. I am using Saxon 5.1 btw, though I doubt the problem stems from there ;-) regards Jeremy ___________________________________________________________________ Jeremy Quinn Karma Divers webSpace Design HyperMedia Research Centre <mailto:jeremy@xxxxxxxxxxxxxxxxx> <http://www.media.demon.co.uk> <phone:+44.[0].207.737.6831> <pager:jermq@xxxxxxxxxxxxxxx> XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
