    Trying to make a 'latest updates' script

    Hi all,

    Im trying to make a macro that will display the latest X pages that have received updates. The hard part I'm having is to make this work correctly with umbraco nodes that do not have a pageview themselves (eg: 2 nodes that help decide the content of the parent node - if one of the child nodes is updated, I'd like to have the parent node be labeled as updated).

    This is what I got so far:

    <xsl:for-each select="$currentPage/ancestor-or-self::node[@level=1]/descendant-or-self::node[string(data [@alias='umbracoNaviHide']) != '1']">
        <xsl:sort select="@updateDate" order="descending"/>

       <xsl:variable name="parent_with_page" select="ancestor-or-self::node[@template != 0][1]"/>

    </xsl:for-each>

    The problem here is that duplicates will appear if multiple of the child nodes (that dont have their own template) have been recently updated.

    Eg: if node Parent has 2 childnodes A and B that have been updated recently, the Parent-node will appear in the list 2 times.

    After alot of experimenting, I came up with a solution which seems to do its job quite well, I'll post it here for reference.

    If anyone has any suggestions/improvements, please let them know.

    <ul id="LatestUpdates">


    <xsl:for-each select="$currentPage/ancestor-or-self::node[@level=1]/descendant-or-self::node[string(data [@alias='umbracoNaviHide']) != '1' and not(@nodeTypeAlias = 'Inschrijving' or @nodeTypeAlias = 'Photo')]">
     <xsl:sort select="@updateDate" order="descending"/>

    <!-- We move up the tree, looking for the first node that is displayable as a page -->
    <xsl:variable name="page" select="ancestor-or-self::node[@template != 0][1]"/>

    <!-- In this page-node, we find the most recent updateDate and store it -->
    <xsl:variable name="page_latest_update">
         <xsl:for-each select="$page/descendant-or-self::node[./ancestor-or-self::node[@template != 0][1]/@id = $page/@id]">
           <xsl:sort order="descending" select="@updateDate"/>
           <xsl:if test="position()=1"><xsl:value-of select="@updateDate"/></xsl:if>
         </xsl:for-each>
    </xsl:variable>


    <xsl:if test="@updateDate = $page_latest_update">
        <li><xsl:value-of select="umbraco.library:FormatDateTime(@updateDate, 'dd/MM/yy')"/> - <a href="{umbraco.library:NiceUrl($page/@id)}"><xsl:value-of select="$page/data [@alias = 'PageHeader']"/></a></li>
    </xsl:if>

    </xsl:for-each>


    </ul>
