I dont understand becouse thes xsl not is able to group by min...

It doesnt display the min value of <supplier>po2</supplier>

Thanks in advance.

Because the loop is sorted ascending you need to consider only the first iteration.

Hope this helps

HI Ivan,

In this case I get only one item

and the response is "po2 110"

not "po2 90"

further the results should be like this one:

pos2 90

pos3 222

pos1 2345

group by min and supplier...

Thanks in advance
Giancarlo.

Sorry Giancarlo I misunderstood you

The following does what you have described

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="GROUP" match="item" use="supplier"/>
<xsl:template match="/">
<xsl:for-each select="root/item[generate-id(.)=generate-id(key('GROUP',supplier))]">
<xsl:for-each select="key('GROUP',supplier)">
<xsl:sort select="totale_finale" data-type="number" order="ascending"/>
<xsl:if test="position() = 1">
<xsl:value-of select="concat(supplier,' ', totale_finale, '
') "/>
</xsl:if>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

sorry for the delay...

just a little sort modification

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="GROUP" match="item" use="supplier"/>
<xsl:template match="/">
<xsl:for-each select="root/item[generate-id(.)=generate-id(key('GROUP',supplier))]">
<xsl:sort select="totale_finale" data-type="number" order="ascending"/>
<xsl:for-each select="key('GROUP',supplier)">
<xsl:if test="position() = 1">
<xsl:value-of select="concat(supplier,' ', totale_finale, '
') "/>
</xsl:if>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

Thanks a lot.
G.
