Re: [xsl] Sum in conjunction with string splitting?

[Steve <subsume@xxxxxxxxx>]

Sorry. Was trying to be brief. =)


Gist of my xsl is like so:
--------

<xsl:stylesheet version='1.0' xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
      xmlns:msxsl="urn:schemas-microsoft-com:xslt"
      xmlns:func-transform="f:func-transform"
      exclude-result-prefixes="xsl func-transform">

      <xsl:import href="../../../Includes/fxsl-MS-1.1/transform-and-sum.xsl" />
      <func-transform:func-transform/>
<xsl:template match="/">
<xsl:variable name="expenses" select="document('remote document')" />
<xsl:call-template name="transform-and-sum">
      <xsl:with-param name="pFuncTransform"
select="document('')/*/func-transform:*[1]"/>
      <xsl:with-param name="pList"
select="$expenses[substring(expense,1,7)='mileage']/expense"/>
  </xsl:call-template>
</xsl:template>

  <xsl:template match="func-transform:*">
      <xsl:param name="arg" select="0"/>
      <xsl:value-of select="$arg" /> <!-- This isn't printing anything -->
      <xsl:value-of select="substring-after($arg, 'mileage')"/>
  </xsl:template>
--

$expenses actually looks like this:

<Expenses>
 <expense>mileage 10</expense>
 <expense>basketball</expense>
 <expense>icing</expense>
 <expense>mileage 40</expense>
</Expense>

-----

Desired output of the call to transform-and-sum = "50"
