Paged List of Child Nodes in Umbraco

We just started looking at Umbraco- and so I’m delving into Macro’s – these are the packaged up chunks of functionality which make your site actually do things and either take the form of XSLT files which process and spit out the contents of your database, or dot net controls.

I found an excellent example XSLT that allows you to create a paginated list of child nodes over on Tim Geyssens “nibble” blog, and I’ve modified it ever so slightly to stop the numerical index rendering if the pagecount is less than 2- so thought I would re-post it!

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [
  <!ENTITY nbsp "&amp;amp;amp;#x00A0;">

  <xsl:output method="xml" omit-xml-declaration="yes"/>
  <xsl:param name="currentPage"/>
  <xsl:template match="/">

    <xsl:variable name="recordsPerPage" select="/macro/recordsPerPage"/>
    <xsl:variable name="pageNumber" >
        <!-- first page -->
        <xsl:when test="umbraco.library:RequestQueryString('page') <= 0 or string(umbraco.library:RequestQueryString('page')) = '' or string(umbraco.library:RequestQueryString('page')) = 'NaN'">0</xsl:when>
        <!-- what was passed in -->
          <xsl:value-of select="umbraco.library:RequestQueryString('page')"/>

    </xsl:variable> &amp;amp;amp;nbsp;

    <xsl:variable name="numberOfRecords" select="count($currentPage/node)"/>

    <!-- The fun starts here -->
      <xsl:for-each select="$currentPage/node [string(data [@alias='umbracoNaviHide']) != '1']">
        <xsl:if test="position() > $recordsPerPage * number($pageNumber) and
position() <= number($recordsPerPage * number($pageNumber) +
$recordsPerPage )">
            <a href="{umbraco.library:NiceUrl(@id)}">
              <xsl:value-of select="@nodeName"/>


    <xsl:if test="$pageNumber > 0">
      <a href="?page={$pageNumber -1}">previous </a>

<xsl:if test="($numberOfRecords > $recordsPerPage)">
    <xsl:call-template name="for.loop">

          <xsl:value-of select="$i" />

      <xsl:if test="$page = $i">

I absolutely love these. They came at the lace wigs are good quality, and very soft. Absolutely love these extensions. I just love this hair. Hair came on time, I waited until after hair extensions uk very full, no shedding and it is been installed for 3 weeks now and yes I jus ordered 3 more bundles. Lol. I definitely recommend this company for your bundles ladies. They are soft, hair bundles on the head for human hair wigs and I would continue to recommend them. I have thinner hair so they cover and blend nicely.
