Hi Kenny,
You are first grouping by <Detail>, and then you
want to do a 2nd level grouping by <City>. IMO, this
seems not very logical! (if I am not understanding
something wrong).
Please try this XSL (this does not provide solution to
your second requirement) -
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="text" version="1.0"
encoding="UTF-8" indent="yes"/>
<xsl:key name="detail-key" match="Detail" use="." />
<xsl:template match="/Root">
<xsl:for-each select="//Detail">
<xsl:if test="generate-id(.) =
generate-id(key('detail-key', .)[1])">
<xsl:value-of select="@no" /><xsl:text>,
</xsl:text><xsl:value-of select="."
/><xsl:text>
</xsl:text>
<xsl:for-each select="key('detail-key', .)">
<xsl:value-of select="../../../../City"
/><xsl:text>
</xsl:text>
<xsl:value-of select="../../Name"
/><xsl:text>
</xsl:text>
</xsl:for-each>
</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

Mukul

Thanks, Andrew
This is very very close to what I need. But the city
name has to be there
only once for all names like:
100, Red
City1
Name1
Name10
Name100
...etc
City2
Name4
Name40
...
200, Blue
City1
Name2
Name20
...
City2
Name5
...
300, Green
City1
Name3
Name30
Name300
Name3000
...
400, Yellow
City2
Name6
...
Is that possible as well?

Hi,
Though I have been working sometime with XSLT, I
am having
trouble with this transformation. Anyone know how
to do this?
The XML source is from a database and is really
really huge
in size, so performance of the transformation is
very critical...
<Root>
<Community>
<City>City1</City>
<A>
<B>
<Name>Name1</Name>
<Info>
<Detail no="100">Red</Detail>
</Info>
</B>
<B>
<Name>Name2</Name>
<Info>
<Detail
no="200">Blue</Detail>
</Info>
</B>
<B>
<Name>Name3</Name>
<Info>
<Detail
no="300">Green</Detail>
</Info>
</B>
</A>
</Community>
<Community>
<City>City2</City>
<A>
<B>
<Name>Name4</Name>
<Info>
<Detail no="100">Red</Detail>
</Info>
</B>
<B>
<Name>Name5</Name>
<Info>
<Detail
no="200">Blue</Detail>
</Info>
</B>
<B>
<Name>Name6</Name>
<Info>
<Detail
no="400">Yellow</Detail>
</Info>
</B>
</A>
</Community>
</Root>
This is the result I need to produce:
100, Red
City1
Name1
City2
Name4
200, Blue
City1
Name2
City2
Name5
300, Green
City1
Name3
400, Yellow
City2
Name6
Heres a stylesheet that will do it. It's a
grouping problem, you just
need to group <Detail> elements by their id
attibute and text content,
then apply templates to only the first one in the
group. Check out
jeni's site for more on grouping
http://www.jenitennison.com
(I've html like tags in the output rather than
whitespace so my IDE can
tidy it for me :) You may want to replace the
ancestor:: use with
another key to help performance)
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:key name="details" match="Detail"
use="concat(@no,'/',.)"/>
<xsl:template match="/">
<root>
<xsl:apply-templates
select="//Detail[generate-id() =
generate-id(key('details',concat(@no,'/',.))[1])]"/>
</root>
</xsl:template>
<xsl:template match="Detail">
<div detail="{concat(@no,', ',.)}">
<xsl:for-each
select="key('details',concat(@no,'/',.))">
<span>
<xsl:value-of
select="ancestor::Community/City"/>,<xsl:text/>
<xsl:value-of
select="parent::Info/preceding-sibling::Name"/>
</span>
</xsl:for-each>
</div>
</xsl:template>
</xsl:stylesheet>
