I don't see any code in this message.

For generic operations on a tree one can use the FXSL function

     f:foldl-tree()

http://fxsl.cvs.sourceforge.net/viewvc/fxsl/fxsl-xslt2/f/func-foldl-tree.xsl?
revision=1.1&view=markup


Here is the test for this function:

This transformation:

<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:f="http://fxsl.sf.net/";
exclude-result-prefixes="f"
>
    <xsl:import href="../f/func-foldl-tree.xsl"/>
    <xsl:import href="../f/func-Operators.xsl"/>

   <!-- This transformation must be applied to:
        ../data/numTree.xml

        Expected result: 66
    -->
    <xsl:output method="text"/>

    <xsl:template match="/">
      <xsl:value-of select="f:foldl-tree(f:add(), f:add(), 0, /*)"/>
    </xsl:template>
</xsl:stylesheet>

when applied on this XML document:


<nums tree-nodeLabel="01">
  <num tree-nodeLabel="02">01</num>
  <num tree-nodeLabel="03">02</num>
  <num tree-nodeLabel="04">03</num>
  <num tree-nodeLabel="05">04</num>
  <num tree-nodeLabel="06">05</num>
  <num tree-nodeLabel="07">06</num>
  <num tree-nodeLabel="08">07</num>
  <num tree-nodeLabel="09">08</num>
  <num tree-nodeLabel="10">09</num>
  <num tree-nodeLabel="11">10</num>
</nums>

produces the wanted result:

66
