XSL Running total help

[Ryan Ness <ryan.ness@gmail.com>]

Here's my XML snip:

<snip>
       <assetWeights name="A" weight=".033"/>
       <assetWeights name="B" weight=".033"/>
       <assetWeights name="c" weight=".033"/>
       <assetWeights name="D" weight=".033"/>
       <assetWeights name="E" weight=".033"/>
       <assetWeights name="F" weight=".033"/>
       <assetWeights name="G" weight=".033"/>
       <assetWeights name="H" weight=".033"/>
       <assetWeights name="I" weight=".033"/>
       <assetWeights name="J" weight=".033"/>
       <assetWeights name="K" weight=".033"/>
       <assetWeights name="L" weight=".033"/>
       <assetWeights name="M" weight=".033"/>
       <assetWeights name="N" weight=".033"/>
       <assetWeights name="O" weight=".033"/>
       <assetWeights name="P" weight=".033"/>
       <assetWeights name="Q" weight=".033"/>
       <assetWeights name="R" weight=".033"/>
       <assetWeights name="S" weight=".033"/>
       <assetWeights name="T" weight=".033"/>
       <assetWeights name="U" weight=".033"/>
       <assetWeights name="V" weight=".033"/>
       <assetWeights name="W" weight=".033"/>
       <assetWeights name="X" weight=".033"/>
       <assetWeights name="Y" weight=".033"/>
       <assetWeights name="Z" weight=".033"/>
       <assetWeights name="AA" weight=".033"/>
       <assetWeights name="BB" weight=".033"/>
       <assetWeights name="CC" weight=".033"/>
       <assetWeights name="DD" weight=".034"/>
</snip>

What I need is to display the largest 8 weight values (in a text file)
and then instead of continuing to display the remaining assetWeights,
I want to add them up, and display the total...

Here's my <for-each> xsl block... Thanks in advance...

<xsl:for-each select="statementData/assetWeights">
          <xsl:sort select="@weight" data-type="number" order="descending"/>
          <xsl:value-of select="position()"/><xsl:text>- </xsl:text>

          <xsl:if test="position() &lt; 9">
            <xsl:text>DET2</xsl:text>
            <xsl:call-template name="rightpad">
              <xsl:with-param name="fieldvalue"
select="string(../../recipient/groupAccount/@gaId)"/><xsl:with-param
name="fieldsize" select="number(10)"/>
            </xsl:call-template>
            <xsl:call-template name="rightpad">
              <xsl:with-param name="fieldvalue"
select="string(../../recipient/indId/text())"/><xsl:with-param
name="fieldsize" select="number(10)"/>
            </xsl:call-template>
            <xsl:call-template name="rightpad">
              <xsl:with-param name="fieldvalue"
select="string(@name)"/><xsl:with-param name="fieldsize"
select="number(50)"/>
            </xsl:call-template>
            <xsl:call-template name="rightpad">
              <xsl:with-param name="fieldvalue"
select="string(@weight)"/><xsl:with-param name="fieldsize"
select="number(5)"/>
            </xsl:call-template>

          </xsl:if>

          <xsl:if test="position() &gt; 8">
            <xsl:text>Add this one up</xsl:text>
          </xsl:if>

          <xsl:text>&#10;</xsl:text>
        </xsl:for-each>
