Hi Ryan,

TIf you know the nodeTypeAlias (e.g. 'Textpage') of your document type, you should use that:

 <xsl:variable name="parentFolderId" select="number($currentPage/ancestor-or-self::Textpage/mediaFolderId)"/>

Otherwise, use the more generic:

 <xsl:variable name="parentFolderId" select="number($currentPage/ancestor-or-self::*[@isDoc]/mediaFolderId)"/>

Hi Ryan,

Sounds like you want what's referred to as the recursive value of that property (i.e., taken from the first ancestor where it's specified)?

You can do that in one select:

<xsl:variable name="mediaFolder" select="$currentPage/ancestor-or-self::*[normalize-space(mediaFolderId)][1]/mediaFolderId" />

@Chriztian

When trying your code, I get this error:

System.Xml.Xsl.XslLoadException: Prefix 'ancestor-or-self' is not defined.

@Dennis, this is the error I get with your code.

System.OverflowException: Value was either too large or too small for an Int32.

Here is my XSLT.... Basically, what I am trying to do is Use the mediaFolderId if it is present for the current page. If not, I want it to use the one from a parent page.

    <xsl:param name="currentPage"/>

    <xsl:variable name="mediaFolderId" select="number($currentPage/mediaFolderId)" />
<xsl:variable name="mediaFolder" select="$currentPage/ancestor-or-self::*[normalize-space(mediaFolderId)][1]/mediaFolderId" />    

    <xsl:template match="/">

        <!-- Displays all images from a folder in the Media Library -->


      <xsl:choose>
    <xsl:when test="number($mediaFolder)">
        <xsl:for-each select="umbraco.library:GetMedia($mediaFolderId, true())/Image">
                    <xsl:if test="umbracoFile !=''">
                    <img src="/{umbraco.library:UrlEncode(umbracoFile)}" class="bgM" />
                    </xsl:if>
                </xsl:for-each>
    </xsl:when>
    <xsl:otherwise>

        <xsl:for-each select="umbraco.library:GetMedia($mediaFolder, true())/Image">
                    <xsl:if test="umbracoFile !=''">
                    <img src="/{umbraco.library:UrlEncode(umbracoFile)}" class="bgM" />
                    </xsl:if>
                </xsl:for-each>

        </xsl:otherwise>
</xsl:choose>

Yeah, sorry 'bout that - writing this on my phone, so had to fix a couple times :)

Should be good now.

The code above is not working. I pasted your code in, but it still doesn't work. Do I have something set up wrong?

Got it working, I didn't change part of the code below in the Choose. Once I updated that to just mediaFolder it started working. Thanks @Chriztian

Just for completion. Here is the working code. Including a default media folder of "4096" if there is nothing selected in the Parent.

    <xsl:param name="currentPage"/>

<xsl:variable name="mediaFolderId" select="number($currentPage/mediaFolderId)" />
<xsl:variable name="mediaFolder" select="$currentPage/ancestor-or-self::*[normalize-space(mediaFolderId)][1]/mediaFolderId" />

<xsl:template match="/">

    <!-- Displays all images from a folder in the Media Library -->


  <xsl:choose>
<xsl:when test="number($mediaFolder)">
    <xsl:for-each select="umbraco.library:GetMedia($mediaFolder, true())/Image">
                <xsl:if test="umbracoFile !=''">
                <img src="/{umbraco.library:UrlEncode(umbracoFile)}" class="bgM" />
                </xsl:if>
            </xsl:for-each>
</xsl:when>
<xsl:otherwise>

    <xsl:for-each select="umbraco.library:GetMedia(4096, true())/Image">
                <xsl:if test="umbracoFile !=''">
                <img src="/{umbraco.library:UrlEncode(umbracoFile)}" class="bgM" />
                </xsl:if>
            </xsl:for-each>

    </xsl:otherwise>

is working on a reply...
