Thank you very much, it works like a charm :-)

You are right, I provided wrong simple result.

Kind regards,

If you want to restrict the grouping to the parent 'item' element then
one way to do that is to integrate the generated id of the 'item'
element into the key, as in the following stylesheet:

<xsl:stylesheet xmlns:xsl="";

     <xsl:key name="role" match="planItemOrganization"
use="concat(generate-id(parent::item), '|', role/name/name)"/>

     <xsl:output method="text" encoding="UTF-8"/>
     <xsl:strip-space elements="*"/>

     <xsl:template match="data">

     <xsl:template match="datasource">

     <xsl:template match="item">
         <xsl:text>Item </xsl:text>
         <xsl:for-each select="planItemOrganization[count(. |
key('role', concat(generate-id(parent::item), '|', role/name/name))[1])
= 1]">
             <xsl:sort select="order"/>
             <xsl:value-of select="role/name/name"/>
             <xsl:for-each select="key('role',
concat(generate-id(parent::item), '|', role/name/name))">
                 <xsl:text>  </xsl:text>
                 <xsl:value-of select="organization/name1/name"/>


However that way I don't get quite the result you described, instead I get

Item 1
   Organization 1
   Organization 2
   Organization 4

   Organization 3
   Organization 5
Item 2
   Organization 5
   Organization 6

   Organization 7
   Organization 8

   Organization 9

when I run the above stylesheet against your XML sample data. The result
however should be what you want, I guess the sample result you provided
did not match the sample input data you provided.
