RE: XML/XSLT formatting problem

Thanks Michael,

This has further been complicated by the fact that I have image ID's in the
result set that are repeated..in what is essentially a de-normalised
structure

Eg. 

<results lastid="9">
  <image>
    <id>37</id>
    <imagetitle>Fred</imagetitle>
    <imagelocation>fred.jpg</imagelocation>
    <imagesubject>Fred</imagesubject>
  </image>
  <image>
    <id>9</id>
    <imagetitle>Wilma</imagetitle>
    <imagelocation>wilma.jpg</imagelocation>
    <imagesubject>Wives</imagesubject>
  </image>
  <image>
    <id>9</id>
    <imagetitle>Wilma</imagetitle>
    <imagelocation>wilma.jpg</imagelocation>
    <imagesubject>Women</imagesubject>
  </image>
  <image>
    <id>9</id>
    <imagetitle>Wilma</imagetitle>
    <imagelocation>wilma.jpg</imagelocation>
    <imagesubject>Fred</imagesubject>
  </image>
  <image>
    <id>22</id>
    <imagetitle>Barney</imagetitle>
    <imagelocation>barney.jpg</imagelocation>
    <imagesubject>Bam Bam</imagesubject>
  </image>
  <image>
    <id>22</id>
    <imagetitle>Barney</imagetitle>
    <imagelocation>barney.jpg</imagelocation>
    <imagesubject>Betty</imagesubject>
  </image>
  <image>
    <id>24</id>
    <imagetitle>Dino</imagetitle>
    <imagelocation>dino.jpg</imagelocation>
    <imagesubject>Dino</imagesubject>
  </image>
  <image>
    <id>24</id>
    <imagetitle>Dino</imagetitle>
    <imagelocation>dino.jpg</imagelocation>
    <imagesubject>Fred</imagesubject>
  </image>
</results>

So what I have is a key on id at the top of my template:

<xsl:key name="idkey" match="image" use="id"/>
..

Then I want to output a line for each unique ID using:

<xsl:for-each select="photographs::[count(. | key('idkey', id)[1])=1]">
..

Is there any way in the above line I can apply the restriction that the id
must be in a sibling of the image with the @lastid so I only output items
with id's of 22 and 24?

Cheers,

Chris
