counting/comparing values

Greetings all,
I am stuck trying to get the highest number of child elements of a
particular type.  What I would like to do is return the count of the most
<entry> elements within a single <row> of a <table>:

<table>
 <tbody>
  <row>
    <entry>1</entry>
  </row>
  <row>
    <entry>1</entry>
    <entry>2</entry>
  </row>
  <row>
    <entry>1</entry>
    <entry>2</entry>
    <entry>3</entry>
  </row>
</tbody>
</table>

The template processing this is:
<xsl:template match="table">
	<table>
	<xsl:variable name="col_count">
	<xsl:for-each select="child::tbody[1]/row">
	    <xsl:choose>
		<xsl:when test="count(preceding-sibling::row/child::entry)
&gt; count(entry)">
			<xsl:value-of
select="count(preceding-sibling::row/child::entry)"/>
		</xsl:when>
		<xsl:otherwise>
			<xsl:value-of select="count(entry)"/>
		</xsl:otherwise>
	   </xsl:choose>
	</xsl:for-each>
	</xsl:variable>
 <xsl:attribute name="col_count"><xsl:value-of
select="$col_count"/></xsl:attribute>
	</table>
</xsl:template>

Which returns:
<table col_count="123"/>

When what I want is <table col_count="3"/>

Any ideas?  Any and all help appreciated.
Thanks, John
