Min/Max from a node set

JakeRogers · November 1st, 2013, 06:20 PM

I'm back!!! Can't use xslt 2.0 because FlightSimulatorX uses 1.0. Can't use min or max functions or Sort since they aren't in 1.0....
Is there any way to use Variables to extract min or max from a nodeset? I've hacked for 2 days now but no luck...here's my xml:
<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type='text/xsl' href='MissionProfile.xsl'?>
<MissionProfile>
<Profile name="BHP" value="290000"/>
<Profile name="EOT" value="356.51129"/>
<Profile name="Cnt" value="5.00000"/>
<Profile name="Fire" value="1"/>
<Profile name="SIMVAR_VERSION" value="V1.0.3537.0"/>

...and my xslt

<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform' version='1.0'>
<xsl:variable name="max1" select="string(.)"/>
<xsl:template match="/MissionProfile">
<html>
<h2>Here's your maximum Dead Reckoning course variation in decimiles:</h2>
<body>
<br/>
<xsl:text>Max Course Variation = </xsl:text>
<xsl:for-each select="Gather/Stat">
<xsl:sort select="Point"/>
<xsl:if test="position()=last()">
<last>"."</last>
</xsl:if>

</xsl:for-each>
<br/>
</body>
</html>
</xsl:template>
</xsl:stylesheet>

Thanks for any help, as I'm approaching burnout, but I know I'm so close to a solution.

You do have the right approach with a for-each, a sort and a check for position(). I suspect you want to change the selection of the for-each:

Code:

<xsl:for-each select="Gather/Stat/Point"> 
     <xsl:sort select="." data-type="number"/>
   <xsl:if test="position()=last()">
        <last><xsl:value-of select="."/></last>
     </xsl:if>
</xsl:for-each>

That would compute the maximum value of the values inside of the Point elements.

Martin, Thank you very much...This is the most user surly language I have ever dealt with! I obviously don't fully understand the structure in spite of hours of reading...Any recommendations? Thanks again, Martin...saved my day!
