Thank you very much, it works like a charm :-)
You are right, I provided wrong simple result.
Kind regards,

Within each "item" I need to group the node "planItemOrganization"

"organization/name1/name". The thing is that values of the role node
are not constant and they may change.
For now the stylesheets finds all roles according to key, groups
organizations right but outputs all in the first item which is not
desired. I am wondering how to restrict the processing to just current
item, so that within each item groups are created in the right way. In
XSLT 2.0 it would be fairly easy, but I am stuck with 1.0...
This is the stylesheet which I succesfully used for grouping in one
record now adapted to process list of records (for better readablity
and simplification I extracted it to ouptut text):
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:key name="role" match="planItemOrganization"
use="role/name/name"/>
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="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<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:apply-templates/>
</xsl:template>
<xsl:template match="datasource">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="item">
<xsl:text>Item </xsl:text>
<xsl:number/>
<xsl:for-each select="planItemOrganization[count(. |
key('role', concat(generate-id(parent::item), '|', role/name/name))[1])
= 1]">
<xsl:sort select="order"/>
<xsl:text> </xsl:text>
<xsl:value-of select="role/name/name"/>
<xsl:text> </xsl:text>
<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"/>
<xsl:text> </xsl:text>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
However that way I don't get quite the result you described, instead I get
Item 1
Orders
Organization 1
Organization 2
Organization 4
Approves
Organization 3
Organization 5
Item 2
Organizes
Organization 5
Organization 6
Executes
Organization 7
Organization 8
Co-operation
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.
