[xsl] Copy excluding some children

[Giacomo <giacgbj@xxxxxxx>]

Is there a way to copy an element excluding some children, at any depth,
using *only* an XPath 2.0 expression without using templates to exclude
such elements?

For example, given:

<A>
   <B>The pen is <C>not</C> on the table</B>
   <D>...</D>
</A>

I want to copy A without C and D obtaining:

<A>
   <B>The pen is on the table</B>
</A>


Thanks,
   Giacomo.
