hi, I've been working with another cms for a couple of years now and recently started testing out umbraco.
 so far I discovered I'm pretty ignorant when it comes to XSLT so that's definetly a study point for me.
 the problem I'm currently having Is I can't seem to get to the data entered with a 'media picker' or a 'multiple media picker'
 I'm using the following code to test it:

 <xsl:value-of select="data [@alias = 'image']"/>

 the code above should display some data entered with a media picker... or so I thought.

<xsl:if test="($currentPage/data[@alias='multi_img']/ descendant::node !='') "> 

 the code above is what I'm using to test if media files have been selected with a multiple media picker.
 I never seem to get past that test. I copied the code from the following page hoping to resolve this but it failed.
 http://umbraco.org/documentation/books/diary-of-a-newbody/rendering-the-output
 
 some extra facts:
 - the media picker in de document type has the name and alias 'image' and has 1 image chosen.
 - the multiple media picker in the document type has the name and alias multi_img and has several images selected.
 - I can retrieve the value of other document type fields, but getiing info media files don't seem to work.
 -  I use the following code in my template to retrieve the image from de media picker without problems:

<umbraco:Item runat="server" field="image" xslt="concat('&lt;img src=&quot;',umbraco.library:GetMedia({0}, true())/data[@alias='umbracoFile'], '&quot; /&gt;')"  xsltDisableEscaping="true"/>

please forgive me if this question has been asked a thousand times (I did search the forum for some clues without success).

any help will be greatly apreciated.
