Subject: Re: [xsl] Merging Alternate readings... From: David Carlisle <davidc@xxxxxxxxx> Date: Mon, 31 Mar 2003 13:24:39 +0100 |
I'm assuming it somehow involves an xsl:for-each based on the contents of body/@wit to create an individual reading for each of these IDREFS, but then how do you merge the duplicate ones back together? yes exactly. If you do the first pass first then merging the things is a standard grouping problem. the solution below uses saxon:node-set to do two passes in a single stylesheet, and also to get a variable that contains the list of ids over which to iterate. (If one id could be a substring of another the contains() test would need to be a bit more careful eg by concatenating a space before testing for teh substring). $ saxon wit.xml wit.xsl <?xml version="1.0" encoding="utf-8"?> <foo> <a id="a1"> <body wit="A C D">This is a test, really.</body> <body wit="B E">This is a testament, really.</body> <body wit="F"/> </a> <a id="a2"> <body wit="A">This is a test, a really long test!</body> <body wit="B C">This is a testament, a really important test!</body> <body wit="D">This is a test, a really boringtest!</body> <body wit="E">This is a testament, a really long test!</body> <body wit="F">This is a different body element</body> </a> </foo> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:saxon="http://icl.com/saxon" extension-element-prefixes="saxon" > <xsl:output indent="yes"/> <xsl:variable name="wits"> <x>A</x> <x>B</x> <x>C</x> <x>D</x> <x>E</x> <x>F</x> </xsl:variable> <xsl:template match="foo"> <foo> <xsl:apply-templates/> </foo> </xsl:template> <xsl:key name="k" match="body" use="."/> <xsl:template match="a"> <a id="{@id}"> <xsl:variable name="a" select="."/> <xsl:variable name="one"> <xsl:for-each select="saxon:node-set($wits)/*"> <body wit="{.}"> <xsl:variable name="x"> <xsl:apply-templates mode="wit" select="$a/node()"> <xsl:with-param name="wit" select="."/> </xsl:apply-templates> </xsl:variable> <xsl:value-of select="normalize-space($x)"/> </body> </xsl:for-each> </xsl:variable> <xsl:for-each select="saxon:node-set($one)/*"> <xsl:if test="generate-id(.)=generate-id(key('k',.))"> <body> <xsl:attribute name="wit"> <xsl:for-each select="key('k',.)"> <xsl:value-of select="@wit"/> <xsl:if test="position()<last()"><xsl:text> </xsl:text></xsl:if> </xsl:for-each> </xsl:attribute> <xsl:value-of select="."/> </body> </xsl:if> </xsl:for-each> </a> </xsl:template> <xsl:template mode="wit" match="*"> <xsl:param name="wit"/> <xsl:if test="not(@wit) or (@wit and contains(@wit,$wit))"> <xsl:apply-templates mode="wit"> <xsl:with-param name="wit" select="$wit"/> </xsl:apply-templates> </xsl:if> </xsl:template> </xsl:stylesheet> ________________________________________________________________________ This e-mail has been scanned for all viruses by Star Internet.
