Hi,

I'm using a standard sitemap XSLT template, but want it to start on level 2 rather than level 1.  Here is the code, starting at level 1, which works perfectly:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:msxml="urn:schemas-microsoft-com:xslt"
  xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon" xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets"
  exclude-result-prefixes="msxml
 umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes 
Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings 
Exslt.ExsltSets ">

<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<xsl:variable name="maxLevelForSitemap" select="4"/>

<xsl:template match="/">
  <xsl:call-template name="drawNodes">  
    <xsl:with-param name="parent" select="$currentPage/ancestor-or-self::* [@isDoc and @level=1]"/>  
  </xsl:call-template>
</xsl:template>

<xsl:template name="drawNodes">
<xsl:param name="parent"/>
  <xsl:if test="umbraco.library:IsProtected($parent/@id,
 $parent/@path) = 0 or (umbraco.library:IsProtected($parent/@id, 
$parent/@path) = 1 and umbraco.library:IsLoggedOn() = 1)">
    <ul>
      <xsl:for-each select="$parent/* [@isDoc and string(umbracoNaviHide) != '1' and @level &lt;= $maxLevelForSitemap]">
        <li>  
          <a href="{umbraco.library:NiceUrl(@id)}">
            <xsl:value-of select="@nodeName"/>
          </a>  
          <xsl:if test="count(./* [@isDoc and string(umbracoNaviHide) != '1' and @level &lt;= $maxLevelForSitemap]) &gt; 0">   
            <xsl:call-template name="drawNodes">    
              <xsl:with-param name="parent" select="."/>    
            </xsl:call-template>  
          </xsl:if>
        </li>
      </xsl:for-each>
    </ul>
  </xsl:if>
</xsl:template>
</xsl:stylesheet>

But when I change this...

<xsl:with-param name="parent" select="$currentPage/ancestor-or-self::* [@isDoc and @level=1]"/>

To this...

<xsl:with-param name="parent" select="$currentPage/ancestor-or-self::* [@isDoc and @level=2]"/>

I get an error:

Error occured

Can anyone suggest what's going wrong?

Thanks!
