Hi Folks,

I am positioned in the XML tree at the first <A> element, within a <parent>
element.

Requirement: There must be only one <A> element within <parent>.

Here are two XPath expressions to check that there is only one <A> element:

	count(../A) eq 1

or

	not(following-sibling::A)

Which XPath expression evaluates faster?
