    Help with correct XPath

    Hi.

    I have a small newslist in my master template, that shows the names of the number of news-articles specified from a textfield ("nyhedsgruppeItems") from a document type called "Nyhedsgruppe".

    It's working when I'm on the "Nyhedsgruppe" page (all news-nodes are childs of "Nyhedsgruppe"), but regardless of which other page I navigate to, it stops working. I can't figure out how to write the correct XPath to get it working.

    Now I have:

    <xsl:variable name="NumberofItemsToDisplay" select="$currentPage/data [@alias = 'nyhedsgruppeItems']" />

     

    nyhedsgruppeItems is an integer telling how many news-articles to display in the newslist.
    Just like this:

     

    <xsl:if test="position()&lt;= $NumberofItemsToDisplay"> <li> <a title="{@nodeName}" href="{umbraco.library:NiceUrl(@id)}"> <xsl:value-of select="umbraco.library:TruncateString(umbraco.library:StripHtml(@nodeName), $MaxNoChars, '...')" /> </a> </li> </xsl:if>

    You are trying to get the news items from the currentPage, but they're not there, so you have to go find them higher up in the tree, like so:

    <xsl:for-each select="$currentPage/ancestor-or-self::node //node[@nodeTypeAlias = 'nyhedsgruppeItems']">

    Hi Stefan,

    How looks your xsl:foreach or apply-template?
    I think the problem lies in the select.

    Sebastiaan,

    Thanks for pointing me in the right direction. Your solution was not quite what I wanted, but your XPath got me going.

    Now I have this variable:

    <xsl:variable name="NumberofItemsToDisplay" select="$currentPage/ancestor-or-self::node //node[@nodeTypeAlias = 'Nyhedsgruppe']/data [@alias = 'nyhedsgruppeItems' ] " />

    That I can call further down my code to get the correct number of items showing from all pages:

    <xsl:if test="position()&lt;= $NumberofItemsToDisplay">

    Thanks for your quick replies!
