Subject: Re: [xsl] access to preceding-sibling in a sorted list From: David Carlisle <davidc@xxxxxxxxx> Date: Tue, 4 Sep 2007 13:38:12 +0100 |
this is easier in xslt2 (where xsl-for-each-group does what you want) in xslt1 there are essentially two approaches. 1 (the "pipeline" approach) first sort the items, not adding the id attributes, but do it into a variable <xsl:variable name="first-pass"> the code to generate a list of <li> elements </xsl:variable> then use the xx:node-set() extension function taht most XSLT1 engines have to allow you to proxcess this, the sorted items now are siblins so you can do <xsl:for-each select="xx:node-set($first-pass)/li"> <xsl:copy> <xsl:if test="...."><xsl:attribute name="id"..... 2 (the grouping approach) View it as a grouping problem, and use one of the XSLt 1 grouping idioms (google for muenchian grouping) for example You want to group on first letter, sort the groups, sort each item in each group and add an attribute on teh first <xsl:key name="l" match="card" use="substring(full-name,1,1)"/> <xsl:for-each select="card[generate-id()=generate-id(key('l',substring(full-name,1,1)))]"> <xsl:sort select="full-name"/> <xsl:variable name="letter" slect="key('l',substring(full-name,1,1)))"/> <xsl:for-each select="key('l',$letter)"> <xsl:sort select="full-name"/> <li> <xsl:if test="position()=1"><xsl:attribute name="id"><xsl:value-of select="$letter/></xsl:attribute> <xsl:value-of select="full-name"/> (untested) David ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
