Hello Everyone,
A while ago I have asked about the lovely Muenchian method to solve a
simple example. Unfortunately I am stuck with something that should be
straight forward. I greatly would appreciate any input on this:
XML Input:
<tree>
<fruit ID="111">
<mango ID="333">
<colour>
<Rate_Structure_Event
ConceptType="Rate_Structure_Event" ID="1"></Rate_Structure_Event>
</colour>
</mango>
<orange ID="222">
<color>orange</color>
</orange>
</fruit>
<fruit_adjustment>
<color>
<Path>
<Steps>111,333</Steps>
</Path>
<bla>false</bla>
<Rate_Event ConceptType="Rate_Event"
ID="A"></Rate_Event>
<Rate_Event ConceptType="Rate_Event"
ID="B"></Rate_Event>
</color>
</fruit_adjustment>
</tree>
XSLT 2.0:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:key name="step" match="fruit_adjustment/color//Rate_Event"
use="../Path/Steps"/>
<xsl:template match="*">
<xsl:copy>
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="fruit_adjustment"/>
<xsl:template match="colour">
<xsl:copy-of
select="(key('step',string-join(ancestor-or-self::*[(_at_)ID]/@ID,',')),.)[1]
"/>
</xsl:template>
</xsl:stylesheet>
My desired XML output:
<tree>
<fruit ID="111">
<mango ID="333">
<Rate_Event ConceptType="Rate_Event"
ID="A"></Rate_Event>
<Rate_Event ConceptType="Rate_Event"
ID="B"></Rate_Event>
</mango>
<orange ID="222">
<color>orange</color>
</orange>
</fruit>
</tree>
However I get this XML Output, what do I do wrong? (Only one Rate_Event
is being copied over, why?)
<tree>
<fruit ID="111">
<mango ID="333">
<Rate_Event ConceptType="Rate_Event" ID="A"/>
</mango>
<orange ID="222">
<color>orange</color>
</orange>
</fruit>
</tree>
I greatly appreciate your help,
Kind Regards
Houman

I believe the problem is in this line:
<xsl:copy-of
select="(key('step',string-join(ancestor-or-self::*[(_at_)ID]/@ID,',')),.)[1]"/>
The section reading
'(key('step',string-join(ancestor-or-self::*[(_at_)ID]/@ID,',')),.)' will
select all matching Rate_Event nodes correctly, as well as the current
node. The predicate at the end '[1]', will then take the first item in
this list. I suspect you want to use some kind of conditional here...
