RE: [xsl] Yet Another Flat File to Hierarchy question..

["McNally, David" <David.McNally@xxxxxxxxxx>]

For some reason I can't get current() to work in key definitions - or at
least that seems to be what the problem is.  Using the suggested key below,
I tried this xslt:


<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
	<xsl:output method="xml" version="1.0" encoding="UTF-8"
indent="yes"/>
<xsl:key name="get-next-level" match="p"
use="generate-id(preceding-sibling::p[@style &lt; current()/@style][1])"/>

<xsl:template match="doc">
	<doc>
		<xsl:apply-templates select="p[@style=1]"/>
	</doc>
</xsl:template>

<xsl:template match="p">
	<xsl:variable name="thisid" select="generate-id(.)"/>
	<p style="{@style}">
		<xsl:apply-templates/>
		<xsl:apply-templates select="key('get-next-level',
$thisid)"/>
	</p>
</xsl:template>
</xsl:stylesheet>

on this xml:

<doc>
	<p style="1">Top Level Heading</p>
	<p style="2">Sub Heading 1</p>
	<p style="3">Sub heading 2</p>
	<p style="3">Sub Heading 3</p>
	<p style="4">Sub Heading 4</p>
	<p style="1">Another Heading</p>
</doc>

and, using saxon 6.4.4, got this output:

<?xml version="1.0" encoding="UTF-8"?>
<doc>
   <p style="1">Top Level Heading</p>
   <p style="1">Another Heading</p>
</doc>

I.e. the key wasn't selecting anything.  With some experimentation it seems
that the key isn't getting set, or is set to '' for all the p elements, and
some simpler key definitions make it seem that it is the current() that is
the culprit.  I get the same results with MSXML.

Is there something I am missing?  Have I made some elementary mistake?  Does
it work for everyone else?

Thanks,
David.
