RE: [xsl] Finding last node in recursive tree

["Woosley, David" <David.Woosley@xxxxxxxx>]

Thanks, but you're missing a key point.  The only common ancestor of all
<dataset> nodes is the root node.  Look at this diagram ...

report
  dataset
    dataset
  dataset
    dataset
      dataset
  dataset
    DATASET

I need to know when I'm starting the 'DATASET' that appears in caps -- the
very last dataset node regardless of depth.

Not sure if I understand you correct but here is what
I think will work. 

you can use something like this


<xsl:if test="count(following-sibling::node())=0">

in the template which matches the <dataset> element.
If there are no more dataset elements following the
current dataset element with the same parent thus
meaning in the same nodeset then this will return a
value true else it will be false.
For example in the following context

    <stuff>
1    <dataset>
2      <dataset>
          <stuff/>
3          <dataset>
             <stuff/>
          </dataset>
4          <DATASET>
             <stuff/>
          </dataset>
          <stuff/>
      </dataset>
    </dataset>
   </stuff>

Thus this will return a value of TRUE for nodes named
1 2 and 4 while it will return FALSE for 3 since it is
not the last dataset element.
Hope this helps.

Good Luck !
