Hi,

I am new to XSLT programming and I am figuring out how this works.

I have a site created in Umbraco and implemented the ImageCropper data type. I have a page that shows subpages as thumbnails (from the default xslt starter templates) and would like to extend this.

I would like to check if there are crops available and if so, use this, else use default thumbnail of the image.

Also I would like to check on the crop item name ("Category Image Thumbnail" for example), because there could be more types later on.

Here is a snippet from the umbraco.conifg file which shows two nodes. one with and one without crops. The furst one should show the umbracoFile, the second the crop

<node id="1061" version="1fca41c1-c058-4415-a7a9-3ca3c912fffb" parentID="1060" level="3" writerID="0" creatorID="0" nodeType="1059" template="1058" sortOrder="1" createDate="2009-10-19T16:57:50" updateDate="2009-10-19T17:17:54" nodeName="Winches" urlName="winches" writerName="Administrator" creatorName="Administrator" nodeTypeAlias="Category" path="-1,1048,1060,1061">

        <data alias="umbracoUrlName" />
        <data alias="umbracoUrlAlias" />
        <data alias="umbracoRedirect" />
        <data alias="umbracoNaviHide">1</data>

            <crop name="Category Image Thumbnail" x="45" y="27" x2="594" y2="439" url="/media/419/cranes_Category Image Thumbnail.jpg" />

            <crop name="otherCrop" x="45" y="27" x2="594" y2="439" url="/media/419/cranes_otherCrop.jpg" />          </crops>
        </data>
        <data alias="umbracoUrlName" />
        <data alias="umbracoUrlAlias" />
        <data alias="umbracoRedirect" />
        <data alias="umbracoNaviHide">1</data>
        <data alias="MetaTitle" />
        <data alias="MetaDescription"><![CDATA[]]></data>
        <data alias="MetaKeywords"><![CDATA[]]></data>
        <data alias="Robots"><![CDATA[]]></data>
      </node>

the template, i think, should be something like this, but i do not know how to check if there are crops available.  Hope somebody can help me out...

<xsl:template match="/">

<!-- The fun starts here -->
<ul class="categories">

<xsl:for-each select="$currentPage/node">
    <xsl:choose>
      <xsl:when test="<!-- crop with name is available -->">

          <li><a class="fthumb" href="{umbraco.library:NiceUrl(@id)}"  title="winches"><img width="140" height="105" alt="winches" src="{concat(substring-before(data [@alias='umbracoFile'],'.'), '_Category Image Thumbnail.jpg')}" /></a></li>

      </xsl:when>
      <xsl:otherwise>
         <li><a class="fthumb" href="{umbraco.library:NiceUrl(@id)}" title="winches"><im g width="140" height="105" alt="winches" src="{data [@alias='umbracoFile']}" /></a></li>
      </xsl:otherwise>
    </xsl:choose>


</xsl:for-each>
</ul>
</xsl:template>
