I have been tasked with 'fixing' a bug in Umbraco whereby 'folder' pages are being shown as hyperlinks in the sitemap page. I have had a crack at both the razor and xslt versions of these sitemap pages but for the life of me I cannot get it to work. All I want to simpy do is if the page in the sitemap tree is a folder type then show it's name as text and if it is a page type then show it's name with a link to the page. I even tried using a custom propert instead called showAsLinkInSitemap with a true/false value to for each node (folder/page) but even this does not work, I just get nothing!

Anyway, here's what I've tried:

<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>  
  <xsl:if test="string(showAsLinkInSitemap) = '1' or string(showAsLinkInSitemap) = 'null'">
    <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>
  </xsl:if>
  
  <xsl:if test="string(showAsLinkInSitemap) = '0'">
    <xsl:value-of select="@nodeName"/>
    <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>  
  </xsl:if>   
  
</li>
</xsl:for-each>
</ul>
</xsl:if>
</xsl:template>

I am a complete amateur when it comes to xslt so no idea how to check for a null value using this language. If anyone could help, at all, I would greatly appreciate it as this has got me totally stumped with what I thought would be such a simple thing to do!
