Not sure exactly what you mean by dynamic path, but one problem with the above is you should just be referencing $imagePosition, not $currentPage/$imagePosition (assuming you are wanting to reference the variable you defined and not a field on the page)
I'm guessing you're trying to name the property that holds the mediaId - so you'll need to use the name() function - here's a slightly rewritten sample to get you going:
<xsl:template match="/">
<!-- Grab the property right away - will not throw exception -->
<xsl:variable name="imagePosition" select="$currentPage/*[name() = /macro/position]" />
<!-- If there was a value -->
<xsl:if test="normalize-space($imagePosition) ">
<xsl:variable name="file" select="umbraco.library:GetMedia($imagePosition, false())" />
<!-- Handle file, whether Image, File, Folder or whatever -->
<xsl:apply-templates select="$file[not(error)]" />
</xsl:if>
</xsl:template>
<!-- Template for Image -->
<xsl:template match="Image">
<img src="{umbracoFile}" width="{umbracoWidth}" height="{umbracoHeight}" alt="{@nodeName}" />
</xsl:template>
Dynamic path in xslt
Hi
Im trying to figure out a way to use a dynamic path in my expressions
<xsl:template match="/">
<xsl:variable name="imagePosition" select="/macro/position" />
<xsl:if test="$currentPage/$imagePosition!='' and number($currentPage/$imagePosition)!=0">
<xsl:variable name="file" select="umbraco.library:GetMedia(number($currentPage/$imagePosition),'false')"/>
<xsl:if test="not($file/error)">
<img src="{$file/umbracoFile}"/>
</xsl:if>
</xsl:if>
</xsl:template>
But ofcourse it fails misserably. Is there an eval of some sort?
Thanks for any input

Looks like $imagePosition is the media item's id so Tom's solution will fix it.
xslt variables are accessed by themselves ($imagePosition)
page properties are accessed as children of the current page ($currentPage/propertyName)
Hi Eric,

Thumbs Up, Eric!
