Question

I have the following xsl template loop (recursive) which calls a VBScript function that takes one parameter which represents the physical hard drive number and retrieves drive information:

<xsl:template name="for.loop.Drives">
<xsl:param name="i" select ="0" />
<xsl:param name="count" />

<!--begin_: Line_by_Line_Output -->
<xsl:if test="$i &lt;= $count">
    <xsl:value-of select="nunit2report2:GetDiskDrives($i)"/>
</xsl:if>

<!--begin_: RepeatTheLoopUntilFinished-->
<xsl:if test="$i &lt;= $count">
  <xsl:call-template name="for.loop.Drives">
    <xsl:with-param name="i">
      <xsl:value-of select="$i + 1"/>
    </xsl:with-param>
    <xsl:with-param name="count">
      <xsl:value-of select="$count"/>
    </xsl:with-param>
  </xsl:call-template>
</xsl:if>

The VBScript function (which I verified works):

Function GetDiskDrives(drivenumber)

      strComputer = "."

      objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
      colItems = objWMIService.ExecQuery("Select * from Win32_DiskDrive")

      'For Each objItem in colItems
      DiskDriveInfo = DiskDriveInfo  & "Name: " & colItems.ItemIndex(drivenumber).Name & _ 
      " -- Model: " & colItems.ItemIndex(drivenumber).Model &  _ 
      " -- Status: " & colItems.ItemIndex(drivenumber).Status &  _ 
      " -- Size: " & Int(colItems.ItemIndex(drivenumber).Size /(1073741824)) & " GB" & _ 
      " -- Number of Partitions: " & colItems.ItemIndex(drivenumber).Partitions
      'Next

      GetDiskDrives = DiskDriveInfo

End Function

The error returned is a type mismatch. It has to do with the $i passed in to the function:

<xsl:if test="$i &lt;= $count">
    <xsl:value-of select="nunit2report2:GetDiskDrives($i)"/>
</xsl:if>

When I do this, it works, but I’m explicitly passing in 1.

<xsl:if test="$i &lt;= $count">
    <xsl:value-of select="nunit2report2:GetDiskDrives(1)"/>
</xsl:if>

I tried converting the passed in $i to an integer in the VBScript using

drivenum = CInt(drivenumber)

but the cast above returns the following error:

System.InvalidCastException: Conversion from type 'XPathDocumentNavigator' to type 'Integer' is not valid.

Anyone know how I can get this call right? I’m using xslt 1.0

Answer 1

Have you tried:

<xsl:value-of select="nunit2report2:GetDiskDrives(number($i))"/>
