It's Andy again!

I have my macro working fine on my home page now but when I use it on a child page the NiceUrl code that I used in it produces a parse error on the child page!? I know it is this bit as if I remove it the content shows as expected!

The 'title' is the page selected with the content picker and 'pageTitle' is the name of the page typed in a TextString!

I'm not sure what to put so that it works on both the home page and a child page?

Please could someone help me with a suggestion? Or a better way to do it?

Thank you very much

Andy

<xsl:template match="/">

<xsl:for-each select="$currentPage/navIcon/data/item">

  <div class="navicon">
    <xsl:if test="position() mod 4 = 0">
      <xsl:attribute name="class">navicon4</xsl:attribute>
    </xsl:if>
      <xsl:variable name="media" select="umbraco.library:GetMedia(icon, false())" />
      <a href="{umbraco.library:NiceUrl(title)}">
         <img alt="{$media/@nodeName}" src="{$media/umbracoFile}" width="{$media/umbracoWidth}" />
      </a>
      <a href="{umbraco.library:NiceUrl(title)}">
         <xsl:value-of select="pageTitle"/>
      </a>
      <p><xsl:value-of select="description" /></p>

Hi Andy

Does the title field also exist on your child page? If it's empty that's probably why you get the error...what happens if you try to amend your for-each from this

<xsl:for-each select="$currentPage/navIcon/data/item">

to

<xsl:for-each select="$currentPage/ancestor-or-self::*/navIcon/data/item">

Does this work?

Hi Andy,

If NiceUrl() is the cause, there must be an <item> element with an empty or non-existent <title>, because that code only executes on <item> elements.

Try the following to debug:

<xsl:template match="/">
    <xsl:for-each select="$currentPage/navIcon/data/item">
        <xsl:variable name="link">
            <xsl:if test="normalize-space(title)">
                <xsl:value-of select="umbraco.library:NiceUrl(link)" />
            </xsl:if>
        </xsl:variable>
        <xsl:variable name="media" select="umbraco.library:GetMedia(icon, false())" />

        <div class="navicon">
            <xsl:if test="position() mod 4 = 0">
                <xsl:attribute name="class">navicon4</xsl:attribute>
            </xsl:if>
            <a href="{$link}">
                <img alt="{$media/@nodeName}" src="{$media/umbracoFile}" width="{$media/umbracoWidth}" />
            </a>
            <a href="{$link}">
                <xsl:value-of select="pageTitle"/>
                <xsl:if test="not($link)"> (has faulty title!)</xsl:if>
            </a>
            <p><xsl:value-of select="description" /></p>
        </div>
    </xsl:for-each>
<xsl:template>
