[xsl] Sorting with variable

[Florian Mueller <jjdm@xxxxxxxx>]

Hello everybody

<xsl:for-each select="//day">
	<xsl:variable name="day" select="."/>
		<xsl:for-each select="//gv/activity[generate-id()=generate-id(key('activity_key',@name))]">
			<xsl:sort select="./hits" data-type="number" order="descending"/>	
			<xsl:variable name="uname" select="@name"/>
			<xsl:variable name="activity" select="$day/gv/activity[@name=$uname]/@name"/>
			<xsl:variable name="summe" select="sum($activity/../..//activity[@name=$uname]/hits)"/>		
			<!-- $summe has the right value -->
			<xsl:sort select="$summe" data-type="number" order="descending"/>	
			<!-- print unsorted -->
			<xsl:value-of select="$summe"/>
		</xsl:for-each>
</xsl:for-each>

My goal is, to sort the "activity" with the "summe". So i want to have for example the following result:

act1                       34
act2                       12
act3                         1

But the script doesnt work. Maybe because i use a variable in the sort-statement?

Anyone knows something about this?

Kindly regards
Florian Mueller
