Question

Filter XSLT results

Answer 1

+2 A:

One naive solution would be to drag along a $done variable and check against that before outputting anything:

<xsl:template name="PrintTitles">
  <xsl:param name="ids"/>
  <xsl:param name="item"/>
  <xsl:param name="done" select="'|'"/>

  <xsl:variable name="itm_id" select="substring-before($ids, '|')"/>

  <xsl:if test="not(contains($done, concat('|', $itm_id, '|'))">
    <xsl:apply-templates select="msxml:node-set($item)/item[contains(fields/field[@key='tags'], $itm_id)]" mode="insure">
      <xsl:with-param name="itm_id" select="$itm_id"></xsl:with-param>                    
    </xsl:apply-templates>
  </xsl:if>

  <xsl:call-template name="PrintTitles">
    <xsl:with-param name="ids" select="substring-after($ids, '|')"/>
    <xsl:with-param name="item" select="$item" />
    <xsl:with-param name="done" select="concat($done, $itm_id, '|')" />
  </xsl:call-template>

</xsl:template>

However, I have a hunch that the whole problem can be solved more elegantly, but without the input XML this is kind of hard.

I'm not at all sure if this works, though. Admittedly I don't know anything about sitecore. Give me some time to read something about it.

Answer 2

A:

Hi Tomalak and others (?)

Sorry for not responding to this question. I figured it out, and made a totaly different XSLT, but now it works.

If someone is interested, I have put in my code down below. But there's alot of it ;)

<xsl:template match="*">

tekst tekst_smal
