Within each "item" I need to group the node "planItemOrganization"
according to "role" and for each role output value represented by
node "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"/>

    <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>
