    Error on saving XSLT file : Expression must evaluate to a node-set.

    Hello,

     

    I'm facing a problem when I want to save an xslt file in the back office.

    I have this error

    System.Xml.Xsl.XslTransformException: Expression must evaluate to a node-set. 
    at System.Xml.Xsl.Runtime.XsltConvert.EnsureNodeSet(IList`1 listItems)

    The XSLT file is :

    <xsl:variable name="rootNode" select="umbraco.library:getHome($currentPage/ancestor-or-self::node [@nodeTypeAlias = 'Home'])"/>
     <li class="toggleSubMenu">
            <a  id="{$rootNode/@id}" class="top_menu" href="{umbraco.library:NiceUrl($rootNode/@id)}">
              Accueil
            </a>
     </li>

    On my developpement PC I can save this file BUT not on my testing environnement ...

    Can anyone help me?

    Thank you.

    Hi Jerome

    I don't know the umbraco.library extension called getHome, and actually I don't think that there's anyone called this unless you developed it yourself (if the extension actually exists, I'd like to know :) ). What should the extension do?

    If you are just trying to create a link to your homepage you can do this:

    <li class="toggleSubMenu">
            <a class="top_menu" href="/">
              Accueil
            </a>
     </li>

    But if you want to grab the homepage with a document type of "Home", you can do like this in the legacy XML schema:

    <xsl:variable name="rootNode" select="$currentPage/ancestor-or-self::node [@nodeTypeAlias = 'Home']"/>

    and like this in the new XML schema:

    <xsl:variable name="rootNode" select="$currentPage/ancestor-or-self::Home"/>

    I hope this helps you out.

    Thank you for your help.

    GetHome is a customised function and there was an error for the name @nodeTypeAlias = 'Home'.

     

    Now its working with the riht name
