I got the following code snippet:

              <xsl:variable name="media" select="umbraco.library:GetMedia($nyhedsbilled, 0)" />
              <textarea cols="40" rows="20">
                <xsl:copy-of select="$media/imageCrop/crops" />
              </textarea>

.. which gives this result:

<crops date="29/10/2010 14:17:59">
<crop name="NyhedPreview" x="11" y="0" x2="90" y2="60" url="/media/4967/lille01_NyhedPreview.jpg" />
<crop name="GalleriPreview" x="11" y="0" x2="90" y2="59" url="/media/4967/lille01_GalleriPreview.jpg" />
<crop name="Galleri800x600" x="10" y="0" x2="90" y2="60" url="/media/4967/lille01_Galleri800x600.jpg" />
</crops>

and that is fine but what I´m trying to get is the url value from the <crop>-node where the name attribute is 'NyhedPreview' so I thought I might try something like this:

<xsl:copy-of select="$media/imageCrop/crops/crop[@name='NyhedPreview'][@url]" />

but that returns the correct <crop>-node with all attributes ???

What am I doing wrong here ?
