XSLT

Hi..

I have a simple set of multiple doctypes in the test condition in a choose element:

<xsl:if test="$currentPage/umbHeadline != ''">
    <xsl:choose>
      <xsl:when test="$currentPage/self::Page or $currentPage/self::CartStep or $currentPage/self::NewsList or $currentPage/self::EventCalendar">
        <h1 class="articleHeading" itemprop="headline name">
          <xsl:value-of select="$currentPage/umbHeadline" disable-output-escaping="yes" />
        </h1>
      </xsl:when>
      <xsl:otherwise>
        <h1 class="articleHeading" itemprop="headline name">
          <a href="{umbraco.library:NiceUrl($currentPage/@id)}"><xsl:value-of select="$currentPage/umbHeadline" disable-output-escaping="yes" /></a>
        </h1>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:if>

Is there an easier way to summarize the line:

$currentPage/self::Page or $currentPage/self::CartStep or $currentPage/self::NewsList or $currentPage/self::EventCalendar

Hi Bjarne,

Yes - use templates :-)

<xsl:template match="/">
    <xsl:apply-templates select="$currentPage[normalize-space(umbHeadline)]" />
</xsl:template>

<xsl:template match="Page | CartStep | NewsList | EventCalendar">
    <h1 class="articleHeading" itemprop="headline name">
        <xsl:value-of select="umbHeadline" disable-output-escaping="yes" />
    </h1>
</xsl:template>

<xsl:template match="*[@isDoc]" priority="-1">
    <h1 class="articleHeading" itemprop="headline name">
        <a href="{umbraco.library:NiceUrl(@id)}"><xsl:value-of select="umbHeadline" disable-output-escaping="yes" /></a>
    </h1>
</xsl:template>

Hi Chriztian..
Thanks..

So the templates replace the choose element? and the priority attribute with -1 behaves as the otherwise element?

And I was trying with seperating the doctypes with | ..
I guess I still need to wrap the <xsl:apply-templatesselect="$currentPage[normalize-space(umbHeadline)]"/> inside the $currentPage/umbHeadline != '' test..

No, the normalize-space() function is already ensuring that templates are applied to the $currentPage only if there is content in the umbHeadline element, so the if-statement is no longer necessary.

As the name implies, normalize-space() normalizes whitespace in the node by stripping away leading and trailing whitespace (among other things). If there is still content left after the normalization, the predicate returns true(), and the templates are applied. Chriztian explained it quite well midway through this comment :)
