Here is part of my xml:

      <FORMPHOTOS>
        <PHOTO NUM="1">
          <FILENAME>09May001.jpg</FILENAME>
          <FILETYPE>JPEG</FILETYPE>
        </PHOTO>
        <PHOTO NUM="2">
          <FILENAME>09005.jpg</FILENAME>
          <FILETYPE>JPEG</FILETYPE>
        </PHOTO>
        <PHOTO NUM="3">
          <FILENAME>09002.jpg</FILENAME>
          <FILETYPE>JPEG</FILETYPE>
        </PHOTO>
      </FORMPHOTOS>

In my xsl sheet I am doing:

 <xsl:template match="FORMPHOTOS/PHOTO">
  <xsl:choose>
   <xsl:when test=". != ''">
    <attachment>
     <source>
      <xsl:value-of select="../PHOTO/@NUM"/>
     </source>
    </attachment>
   </xsl:when>
  </xsl:choose>
 </xsl:template>

In my source tag I am actually doing a little more but I am trying to get 
the value of @NUM from the immediately preceding node.

But this gets me '1' for all three PHOTOs.

I want to get '1' for the first PHOTO, '2' for the 2nd PHOTO and '3' for the 
3rd PHOTO.

It seems to always get the first one instead of the immediately preceding 
one.

Thanks,

Tom
