Hi,
This is the XML to transform:
<?xml version="1.0" encoding="UTF-8"?>
<ROWSET>
<ROW>
<ID>27835</ID>
<NUMBER>29715</NUMBER>
<PHONE>09876</PHONE>
<ACT>ACT34</ACT>
</ROW>
<ROW>
<ID>27835</ID>
<NUMBER>29716</NUMBER>
<PHONE>62784</PHONE>
<ACT>ACT87</ACT>
</ROW>
<ROW>
<ID>27835</ID>
<NUMBER>29716</NUMBER>
<PHONE>3333333</PHONE>
<ACT>ACT23</ACT>
</ROW>
<ROW>
<ID>27835</ID>
<NUMBER>29716</NUMBER>
<PHONE>3333333</PHONE>
<ACT>ACT111</ACT>
</ROW>
</ROWSET>
First I want to group in a first level with the same
ID,NUMBER. Inside of
this first group, a second group with a second
group with PHONE. And finally a third group, inside the
second group with
ACT. I'm not sure if I'm explainig clear.

My desired output for the first XML is:
<?xml version="1.0" encoding="UTF-16" ?>
<ROOT xmlns:xalan="http://xml.apache.org/xslt";>
<ID>27835</ID>
<NUM>29715</NUM>
<PHONE_DATA>
<PHONE>09876</PHONE>
<ACT_DATA>
<ACT>ACT34</ACT>
</ACT_DATA>
</PHONE_DATA>
<ID>27835</ID>
<NUM>29716</NUM>
<PHONE_DATA>
<PHONE>3333333</PHONE>
<ACT_DATA>
<ACT>ACT23</ACT>
</ACT_DATA>
<ACT_DATA>
<ACT>ACT111</ACT>
</ACT_DATA>
</PHONE_DATA>
<PHONE_DATA>
<PHONE>62784</PHONE>
<ACT_DATA>ACT87</ACT_DATA>
Should this not be
<ACT_DATA>
<ACT>ACT87</ACT>
</ACT_DATA>
Like in the other ACT_DATA elements?
</PHONE_DATA>
</ROOT>
If the all ACT_DATA should contain ATC, then
<xsl:key name="level1" match="ROW" use="concat(ID, ' ', NUMBER)"/>
<xsl:key name="level2" match="ROW" use="concat(ID, ' ', NUMBER, ' ', PHONE)"/>
<xsl:template match="ROWSET">
<ROOT>
<xsl:for-each select="ROW[generate-id(.) = generate-id(key('level1',
concat(ID, ' ', NUMBER)))]">
<xsl:sort select="ID"/>
<xsl:copy-of select="ID"/>
<NUM>
<xsl:value-of select="NUMBER"/>
</NUM>
<xsl:variable name="group" select="concat(ID, ' ', NUMBER)"/>
<xsl:for-each select="../ROW[generate-id(.) = generate-id(key('level2',
concat(ID,' ',NUMBER, ' ', PHONE))) and concat(ID, ' ', NUMBER) = $group]">
<xsl:sort select="PHONE"/>
<PHONE_DATA>
<xsl:copy-of select="PHONE"/>
<xsl:for-each select="key('level2', concat(ID,' ',NUMBER, ' ',
PHONE))/ACT">
<ACT_DATA>
<xsl:copy-of select="."/>
</ACT_DATA>
</xsl:for-each>
</PHONE_DATA>
</xsl:for-each>
</xsl:for-each>
</ROOT>
</xsl:template>
Will get you there, but there are probably better solutions.
Cheers,
Jarno
