I'd like to group this xml by tipo =

This is the xml

<?xml version="1.0" encoding="ISO-8859-1"?>
 <NewDataSet>
 <ENTRADA>
<NOMBRE tipo="JAR"><![CDATA[oorpsvneg.jar]]></NOMBRE>
<F20071023><![CDATA[20071023]]></F20071023>
</ENTRADA>
<ENTRADA>
<NOMBRE tipo="XML"><![CDATA[oorprc00030.xml]]></NOMBRE>
<F20071023><![CDATA[20071023]]></F20071023>
</ENTRADA>
<ENTRADA>
<NOMBRE tipo="JSP"><![CDATA[OORPVE01301_es.jsp]]></NOMBRE>
<F20071023><![CDATA[20071023]]></F20071023>
</ENTRADA>
</ENTRADA>
<ENTRADA>
<NOMBRE tipo="DAT"><![CDATA[REGIONES_ES_ES.PROPERTIES]]></NOMBRE>
<F20071023><![CDATA[20071023]]></F20071023>
</ENTRADA>
<ENTRADA>
<NOMBRE tipo="JSP"><![CDATA[OORPVE02101_es.jsp]]></NOMBRE>
<F20071023><![CDATA[20071023]]></F20071023>
</ENTRADA>
</NewDataSet>

And this is the xsl:

<xsl:stylesheet version="1.0"
    xmlns="urn:schemas-microsoft-com:office:spreadsheet"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >



<xsl:template match="/">

<xsl:processing-instruction name='mso-application'>
		<xsl:text>progid='Excel.Sheet'</xsl:text>
	</xsl:processing-instruction>

</xsl:template>


<xsl:template match="/*">
  <Worksheet>
    <Table x:FullColumns="1" x:FullRows="1">
      <xsl:apply-templates/>
    </Table>
  </Worksheet>
</xsl:template>

<xsl:template match="/*/*">
  <Row>
    <xsl:apply-templates/>
  </Row>
</xsl:template>

<xsl:template match="/*/*/*">
          <Cell>
                <xsl:apply-templates  select="."/>
          </Cell>
</xsl:template>
</xsl:stylesheet>

I'm trying this
<xsl:template match="/*/*">
<xsl:for-each-group  select="*"  group-by="@tipo">
  <Row>
    <xsl:apply-templates/>
  </Row>
</xsl:for-each-group>
</xsl:template>

but it doesn't work...

Is there somebody to help me. Thank you
