RE: Xpath problem?

After further testing, I realize that the template "max" isn't being
called at all. I changed the value when there are no nodes from NaN to
MAX, but it continues to display NaN. However, changes I make to the xsl
outside of that template work.

If possible, I'm more confused than I was before. The template named max
should be called by call-templates name="max", right? Other places in
the xsl call templates the same way, and work fine. Anyone have any
ideas?

Subject:  Xpath problem?

I am using an integration of Apache Ant and Apache JMeter that comes
with xsl files to process the results of a JMeter test. Knowledge of
either of these programs shouldn't be necessary to answer my question.

Almost the entire report (html format) generates correctly, except for
some instances where two specific templates are called, with preselected
nodes passed in.

Here are some snippets of the code:
...
<xsl:variable name="allMaxTime">
  <xsl:call-template name="max">
    <xsl:with-param name="nodes" select="/testResults/*/@t" />
  </xsl:call-template>
</xsl:variable>
...
<xsl:template name="max">
  <xsl:param name="nodes" select="/.." />
  <xsl:choose>
    <xsl:when test="not($nodes)">NaN</xsl:when>
    <xsl:otherwise>
      <xsl:for-each select="$nodes">
        <xsl:sort data-type="number" order="descending" />
        <xsl:if test="position() = 1">
          <xsl:value-of select="number(.)" />
        </xsl:if>
      </xsl:for-each>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>
...
----------------------------------------------------------------------
And the xml looks like this:
<testResults version="1.2">
  <httpSample t="290" lt="0" ts="1151499119860" s="true"
              lb="ATO Summit Home" rc="302" rm="Moved Temporarily"
              tn="Thread Group 1-1" dt="">
    <assertionResult>
      <failure>false</failure>
      <error>false</error>
    </assertionResult>
  </httpSample>
...
</testResults>

The problem is, even though i have multiple entries of these
httpSamples, the result of the "max" template always is NaN, even though
a max value should be returned.

If I take the for-each loop outside the template, and run it without
calling the template, it works fine, and the select="/testResults/*/@t"
is used in other places in the XSL that work.

If anyone can tell me what the error is, and what the code should like
like instead, I would be very grateful.
