Dimitre,
Incredibly helpful .txt file on the issue, but I seem to be
misapplying it. Do you see any obvious errors?
I don't get the underlying logic, so it could be that my use of
$expense instead of a source doc is my problem. Less likely is the
fact that I'm using fxsl-MS.
<xsl:call-template name="transform-and-sum">
<xsl:with-param name="pFuncTransform"
select="document('')/*/func-transform:*[1]"/>
<xsl:with-param name="pList"
select="$expenses[substring(expense,1,7)='mileage']/expense"/>
</xsl:call-template>
<xsl:template 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>
$expense does indeed contain something like:
<Expenses>
<expense>mileage 50</expense>
<expense>mileage 20</expense>
<expense>mileage 30</expense>
</Expense>

With FXSL2.0 one would simply write:
sum(f:map(f:compose(f:decimal(),
f:flip(f:substring-after(),' ')
),
/*/*[contains(.,' ')]
)
)
Or simply use the f:transform-and-sum() function:
f:transform-and-sum(f:flip(f:substring-after(),' '),
/*/*[contains(.,' ')]
)
In XSLT 1.0, one can use the "transform-and-sum" template of FXSL 1.x
