[xsl] variables numbers and apply templates

[Gerrit Kuilder <gkuilder@xxxxxxxxxxxx>]

Hi All,

this has kept me busy for an hour or two, have found a solution but I would like to find out what I ran into.

I wrote a recursive template which I pass as a parameter,  a number

<xsl:template match="sect1|sect2|sect3|sect4|sect5" mode="createtoc">
  <xsl:param name = "TocLevel" />
  <xsl:variable name="CurrLevel">toclevel<xsl:value-of select="$TocLevel></xsl:variable>
  <xsl:variable name="NextElement" select="concat('sect',$TocLevel+1)"/>
 <xsl:element name="{$CurrLevel}">
<xsl:if test="$NextElement">
<xsl:apply-templates select="*[name()=$NextElement]" mode="createtoc">
        <xsl:with-param name = "TocLevel"  select="$TocLevel+1"/>
    </xsl:apply-templates>
  </xsl:if>
  </xsl:element>

Two things I cant'do
a) <xsl:if test="count($NextElement)>0">
b) <xsl:apply-templates select="$NextElement" mode="createtoc">

I have no idea why I get errors when I try the above
if $NextElement would have been only characters :'secttwo' I would have no problem doing the above.

if I declare the varaible as   <xsl:variable name="NextElement" select="sect2"/> it is ok too
I could read out the values with value-of select='$NextElement'

I played around with both versions of declaring the variable  to no avail.

Wondering minds need to know....

Regards

Gerrit
