This parses as count( (.//entry) | (e) )
and should return the sum of the number of descendant "entry" elements and
the number of child "e" elements. If you want to include descendant "e"
elements, write
count(.//entry | .//e)
or (probably more efficient, because a union involves elimination of
duplicates, which is not actually needed here)
count(.//entry) + count(.//e)

It will, because this expression is equivalent to
count((./e) | (./entry))
