Hi Claus,

If you check 1 and 2 on the listing page, do you want pages that have both of these checked (AND), or pages that have either checked (OR) ?

They're stored as a comma-separated list of values, right?

Are they node ids?

/Chriztian

OR

Yes, comma seperated values from the built in checkbox datatype

no, strings

Hi Claus,

I always try to break these down into "puzzle parts", so here's how I'd approach it:

<!-- Simpler access to the nodes we need to filter -->
<xsl:variable name="possibleNodes" select="umbraco.library:GetXmlNodeById($source)/node[not(data[@alias = 'umbracoNaviHide'] = 1)]" />

<!-- List of types we want to find -->
<xsl:variable name="refTypesToShow" select="umbraco.library:Split($currentPage/data[@alias = 'reftype'])" />

<!-- Now find them (this *may* not work - may need to do a for-each on $refTypesToShow/value instead) -->
<xsl:variable name="nodesToShow" select="$possibleNodes[contains(data[@alias = 'reftype'], $refTypesToShow/value)]" />

/Chriztian 

Ok, so to bring it a step further i the puzzle, my intuition tells me something like this: (btw, you have to supply a 'split by' character, dont you? ",',")

<!-- Simpler access to the nodes we need to filter -->
<xsl:variable name="possibleNodes" select="umbraco.library:GetXmlNodeById($source)/node[not(data[@alias = 'umbracoNaviHide'] = 1)]"/>

<!-- List of types we want to find -->
<xsl:variable name="refTypesToShow" select="umbraco.library:Split($currentPage/data[@alias = 'reftype'],',')"/>

<!-- Now find them (this *may* not work - may need to do a for-each on $refTypesToShow/value instead) -->
<xsl:variable name="nodesToShow" select="$possibleNodes[contains(data[@alias = 'reftype'], $refTypesToShow/value)]"/>

<!-- Liting the nodes -->
<xsl:for-each select="nodesToShow/node">
<xsl:value-of select="@nodeName"/>
</xsl:for-each> 

But it doesnt render anything doing this...

Ha - yes you do - good catch :-)

You should strip the /node part from the for-each - $nodesToShow is a set of all the matching nodes at that point:

<!-- Listing the nodes -->
<xsl:for-eachselect="$nodesToShow">
<xsl:value-ofselect="@nodeName"/>
</xsl:for-each>

If this doesn't do it, we need to do it a little backwards (the C# way :-) and run through the $refTypesToShow values...

/Chriztian 

- And that would be something like this:

<!-- Run through the list of values requested, listing nodes that match -->
<xsl:for-each select="$refTypesToShow/value">
    <xsl:variable name="nodesWithThisValue" select="$possibleNodes[contains(data[@alias = 'reftype'], current())]" />

    <h2><xsl:value-of select="." /></h2>

    <xsl:for-each select="$nodesWithThisValue">
        <p><xsl:value-of select="@nodeName" /></p>
    </xsl:for-each>

</xsl:for-each>

- But this approach will get you duplicates, which the other (if working) wouldn't. Sets are awesome in that way.

/Chriztian

Ok, so approach 2 works, but splits the list in segments with duplicates, as you mentioned...

How do we fix that? I really just need one long list without duplicates...

Cool It seems to do the trick, To sum it up:

<!-- Access to the nodes we need to filter -->
<xsl:variable name="possibleNodes" select="umbraco.library:GetXmlNodeById($source)/node[not(data[@alias = 'umbracoNaviHide'] = 1)]" />

<!-- List of types we want to find -->
<xsl:variable name="refTypesToShow" select="umbraco.library:Split($currentPage/data[@alias = 'reftype'],',')" />

<!-- Create an XML variable of <nodeId> elements -->
<xsl:variable name="nodesProxy">
        <xsl:for-each select="$refTypesToShow/value">
                <xsl:for-each select="$possibleNodes[contains(data[@alias = 'reftype'], current())]">
                        <nodeId><xsl:value-of select="@id" /></nodeId>
                </xsl:for-each>
        </xsl:for-each>
</xsl:variable>

<!-- Make XPath navigation in the variable possible -->
<xsl:variable name="nodeIds" select="msxml:node-set($nodesProxy)" />

<!-- Run through the set of nodes that have a nodeid in the set of ids -->
<xsl:for-each select="$possibleNodes[@id = $nodeIds/nodeId]">
        <p>
                <xsl:value-of select="@nodeName" />
        </p>
</xsl:for-each>

is working on a reply...
