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()<=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!
