first n nodes from a current-group

Hi All,

I did a transformation of a XML file.The description is given below-

input XML

<?xml version="1.0" encoding="ISO-8859-1"?>
<School>
<student rec='1'>
<name>Robart J</name>
</student>
<student rec='2'>
<name>Alex M; Peter R; Robart J</name>
</student>
<student rec='3'>
<name>Alex M;Robart J; Dave T</name>
</student>
<student rec='4'>
<name>Alex M;Robart J; Peter R</name>
</student>
</School>

XSLT , I used-

<School>
<xsl:for-each-group select=" School/student group-by="name/tokenize(.,
';\s*')">
<xsl:sort data-type="number" select="count(current-group())"
order="descending" />
<xsl:sort select="current-grouping-key()"/>
<xsl:for-each select="current-group()" >
<xsl:if test="position()=2">
<name count="{count(current-group())}">
<xsl:value-of select="current-grouping-key()"/>
</name>
</xsl:if>
</xsl:for-each>
</xsl:for-each-group>
</School>

I m getting output like-
<School>
<name count='4'>Robart J</name>
<name count='3'>Alex M</name>
<name count='2'>Peter R</name>
</School>

That is all the name elements having more than or equal to 2 count
value.

But I wanted only the first two name elements having highest counts.
that is output like:


<School>
<name count='4'>Robart J</name>
<name count='3'>Alex M</name>
</School>

Please help me to do the same.
Thanks in advance.

Manish
