RE: Selecting specific portions of a tree.

Hi

Both answers were correct, just the fact that one gives you pointers on
how to continue ( which in my opinion is better since it forces you to
look and learn) and another one gives you the complete solution doesn't
give you the right to start to take a stab at Emannuil .

Just my 2 cents, people take time to answer your question, they all do
this at free will, so no need for this kind of remarks

Thanks very much, that was perfect and a lot better response than that
other person Emmanuil Dalsis.

Thanks!

        <child ..../>
</root>

what is the XSL expression to select the 3rd to the 8th child of
root?

If your current node is the element <root> then the XPath expression
is:

    select="child[ position()>=3 and position()&lt;=8 ]"

Any XPath expression can be in a predicate ... if the expression
evaluates 
to a boolean true, then the node being tested is considered still in
play 
... in the above example I have a boolean expression in the predicate
based 
on the current node list selected by addressing all of the elements
named 
<child> along the child:: axis.

Note there are no circumstances in which a naked less-than character
is 
allowed in an attribute, hence, I've escaped it above.

This happens to be one of the exercises in our hands-on material.

I hope this helps!
