[xsl] Tool that measures the performance of an XSLT program at a fine granularity?

Hi Folks,

Here is a statement in my XSLT program:

<xsl:variable name="who-list" select="random:sequence($hiddennodes *
$outputnodes, 0.0, math:pow($hiddennodes, -0.5))" as="xs:double*" />

I would like to know the time required to execute each of these portions of
that statement:

(1) math:pow($hiddennodes, -0.5)

(2) $hiddennodes * $outputnodes

(3) random:sequence($hiddennodes * $outputnodes, 0.0, math:pow($hiddennodes,
-0.5))

(4) Time required to assign the variable the value

(5) Time required to ensure the value of the variable is a sequence of zero or
more xs:double values

Is there a tool that provides such fine-grain performance measurements?

/Roger
