You might try using selection to collect top ten and sort ...

Something like this might work:
    <xsl:template match="/">
	<xsl:apply-templates select="/onderwerpen[position()<11]">
		<xsl:sort select="@datum"/>
	</xsl:apply-templates>
    </xsl:template>

    <xsl:template match="onderwerpen">
	<!-- do stuff for each onderwerpen -->
    </xsl:template>

I'm not sure if the sort happens before or after the selection. You may
need to do this in two passes.

Hope that helps.

Subject: [xsl] Sorting XML and select top 10

I would like to sort an XML source. Then select the first 10 of the
sorted list being the 10 newest articles
I've come up with this XSLT so far, but it does not work (it sorts on
'onderwerp', the subject of the for-each)
<xsl:template match="onderwerpen" >
       <xsl:variable name="teller">0</xsl:variable>
     <xsl:for-each select="onderwerp">
        <xsl:sort select="onderwerp/@datum" order="descending"/>
        <xsl:if test="$teller &lt;= 10">
            <xsl:variable name="teller"><xsl:value-of
select="$teller+1"/></xsl:variable>
	       <item>
		  	 <title>
     	       	<xsl:value-of select="@titel"/>
			 </title>
			 <link>
     	       	<xsl:value-of select="@menu"/>
     	       	<xsl:text>_</xsl:text>
     	       	<xsl:value-of select="@beveiliging"/>
     	       	<xsl:text>_</xsl:text>
     	       	<xsl:value-of select="@bestand"/>
     	       	<xsl:text>.html</xsl:text>
			 </link>
     	     <xsl:apply-templates select="inleidingtekst"/>
     	     <pubDate>
     	        <xsl:value-of select="@datum"/>
     	     </pubDate>
		   </item>
		</xsl:if>
     </xsl:for-each>
   </xsl:template>

Anybody having suggestions how to do this?
