[xsl] Problem with keys in for-each (?)
Subject: [xsl] Problem with keys in for-each (?) From: Don Bruey <dbruey@xxxxxxxxxxxxxxxxxxxxx> Date: Tue, 13 Mar 2001 14:10:23 -0500 |
In the following XSLT, I have a key() function called to look up a specific element in the key. If I call this alone, as it is in the first line of the template for "/", it works and I get the output I expect. If I do the EXACT same thing within the loop, I get no output as a result of the apply-templates. The for-each loop is getting executed the appropriate number of times. The results are the same for MSXML3 and Saxon. Any ideas? <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:xbrl="http://www.xbrl.org/core/2000-07-31/metamodel" xmlns:xsd ="http://www.w3.org/1999/XMLSchema"> <xsl:variable name="taxonomy" select="document('AlteredTaxonomy.xml')" /> <xsl:key name="itemKey" match="//*[local-name() = 'item']" use="ancestor-or-self::*[@type][1]/@type" /> <xsl:template match="/"> <!-- this apply-templates call works fine and calls the template below correctly --> <xsl:apply-templates select="key('itemKey', 'ci:entityInformation.businessDescription')" /> <xsl:for-each select="$taxonomy//element" > <!-- xsl:number does output something the number of times I would expect, so I know this loop is getting executed --> <xsl:number /><BR/> <!-- nothing is generated by this call this time - it's exactly the same as the above apply-templates call... Why? --> <xsl:apply-templates select="key('itemKey', 'ci:entityInformation.businessDescription')" /> </xsl:for-each> </xsl:template> <xsl:template match="*"> do something here </xsl:template> I want to create a variable within the for-each loop with the correct key and look that up - but since I can't get past this issue, I can't use the variable as the key either, which is why this bizarre hardcoded XSLT is what I currently am working with.
