    Tree Multi Picker - Can't list out media nodes

    I used the code provided by the best practice for listing download files post, but I'm not getting any output when I try and list out my download files.

    My XSLT looks like this:

    <xsl:template match="/">        
            <xsl:if test="string($currentPage/data [@alias='Files']) != ''">
                <ul class="nav">
                    <xsl:variable name="documentNodeSet" select="$currentPage/data [@alias='Files']"/>

                    <xsl:value-of select="$documentNodeSet/descendant::node"/>
                    
                    <xsl:for-each select="$documentNodeSet/descendant::node">
                        <li>
                            <a href="{umbraco.library:GetMedia(current(), 'false')/data [@alias='umbracoFile']}">
                                <xsl:value-of select="umbraco.library:GetMedia(current(), 'false')/@nodeName" />
                            </a>
                        </li>
                    </xsl:for-each>
                </ul>
            </xsl:if>
        </xsl:template>

    If I do a value-of and select the 

    string($currentPage/data [@alias='Files'])

    all I get are the ids of the two uploaded files (example output - 123,124)

    Anybody have any ideas why this isn't working?

    Hi Matt,

    Two things:

    1. By using "current()" you're sending the actual node into the GetMedia() method - you need to send the id, which should be on a data element under that node.
    2. You need to use false() or 0 (zero) instead of 'false' to not have have GetMedia() return childnodes as well   

    Oh, and one more thing: Make sure you at least cache the call to GetMedia in a variable, so you're not calling it more than necessary

    /Chriztian

    PS: Also, try searching the Wiki for GetMedia()

    Thanks for the response Chriztian.  The problem I'm having is that my for-each produces no data at all. No nodes, nothing.  Any ideas why 

     <xsl:variable name="documentNodeSet" select="$currentPage/data [@alias='Files']"/>

    won't give me nodes to iterate through?

    I think I might see one issue.  The field "Files" only holds the comma seperated list of media file ids.  How can this be considered a node?  Might be a newbie question, just trying to figure out how I can work with this Tree Multi Picker data type.

    Are you sure they are comma seperated? Did you do value-off If you do copy-of, it will output the real underlying XML.

    If it is a comma seperated string, you can easily split them like so:

    <xsl:variable name="files" select="umbraco.library:Split($params, ',')" />

    Again, use something like:

    <xsl:copy-of select="$files" />

    That would give you the xml fragment that you can work with.

    doing a copy-of gives me: 1160,1161

    Great, so all you have to do now is the split and start using the values from there :-)

    Oh you should use

    $currentPage/data [@alias='Files']

    Where my code says $params

    OK!  Thanks Sebastian.  Here is what the working solution looks like for listing files out with the Tree Multi Picker package.

    <xsl:if test="string($currentPage/data [@alias='Files']) != ''">
                <h4>Download Files</h4>
                <ul class="fileList">
                    <xsl:variable name="documentNodeSet" select="umbraco.library:Split(string($currentPage/data [@alias='Files']), ',')"/>                

                    <xsl:for-each select="$documentNodeSet//value">
                        <li>
                            <a href="{umbraco.library:GetMedia(current(), false())/data}">
                                <xsl:value-of select="umbraco.library:GetMedia(current(), 'false')/@nodeName" />
                            </a>
                        </li>
                    </xsl:for-each>
                </ul>
            </xsl:if>
