Why do you have to do this?  Perhaps I'm missing something, but it's
not clear why you can't just follow Michael's advice and do this in a
more declartive way.

Lets say you have the following XML (I have no idea what MSProject looks
like)

<doc>

<hardware>

<task type="a">12</task>
<task type="b">12</task>
<task type="a">22</task>

</hardware>

<software>
<task type="a">2</task>
<task type="b">42</task>
<task type="a">5</task>
</software>

<analysis>
<task type="a">1</task>
<task type="b">3</task>
<task type="a">2</task>

</analysis>

</doc>

The following xslt script will give you totals for the value in each
catagory and the grand total.
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

version="1.0">

  <xsl:output method="text" />

  <xsl:param name="type" select="'a'" />

  <xsl:template match="/doc">
    Value of hardware: <xsl:value-of select="sum(hardware/task[@type=$type])"
/>
    Value of software: <xsl:value-of
select="sum(software/task[@type=$type])" />   Value of analysis:
<xsl:value-of select="sum(analysis/task[@type=$type])" />
  Grand Total: <xsl:value-of select="sum(*/task[@type=$type])" />
  </xsl:template>


</xsl:stylesheet>


If you really need to do this in a more procedural way, use some
recursion, have a template that takes two parameters, a node set and a
value.  Call the same template with the node set of all the other
nodes (position > 1) and the value increased by the amount in the
first node.  Do this until no nodes are in the list and print the
list.
