Umbraco "Error Parsing XSLT File"

Question

I built a website using Umbraco 4.9.0 and all is well locally. I published it and run it from IIS. But it now works, except that for XSLT file (Breadcrumb) referenced on the landing page it says "Error Parsing XSLT File {xslt file name}".

Error is: 'Error parsing XSLT file: \xslt\SiteBreadcrumb.xslt'

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE xsl:stylesheet [

   <!ENTITY nbsp "&#x00A0;"> ]> <xsl:stylesheet   version="1.0"

   select="1"/>   <xsl:template match="/">
       <xsl:if test="$currentPage/@level &gt; $minLevel">
         <tr>
           <xsl:for-each select="$currentPage/ancestor::* [@level &gt; $minLevel and string

(umbracoNaviHide) != '1']">
             <td style=" height: 24px;">
               <a href="{umbraco.library:NiceUrl(@id)}?nodeId={@id}" style="color:black;">
                 <xsl:value-of select="@nodeName"/>
               </a>
               &gt;
             </td>
           </xsl:for-each>
         </tr>
       </xsl:if>   </xsl:template> </xsl:stylesheet>

Does anybody have any idea why all the XSLT files won't parse?

Answer 1

The error is on this instruction:

   <xsl:if test="$currentPage/@level &gt; $minLevel">

Saxon 6.5.5 says:

Error at xsl:if on line 21 of file:/(Untitled): The value is not a node-set

One possible solution is to replace:

<xsl:param name="currentPage"/>

with:

<xsl:param name="currentPage" select="/.."/>

so that now the XSLT processor knows that $currentPage contains a node.
