For example, having this:
<AAA>
  <BBB/>
  <CCC/>
  <DDD/>
</AAA>
I'd like to return AAA with only BBB and CCC elements...

But what is the criterion that designated BBB and CCC?
You could go by name:
select="AAA|AAA/*[name()='BBB' or name()='CCC']"
You could go by position:
select="AAA|AAA/*[position() &lt; 3]"
Or if BBB and CCC had a certain attribute, you could test for it.

In any case, this is a generic XPath question, so you could ask it on
xsl-list or in comp.text.xml and get more answers.
