I'm afraid that's the only way you can find out how many children are in
an Element.

getChildren() returns a List. The List interface has a method called
get(int index)
which you can use if you need random access to the list. However if you
wish to iterate through the list, an Iterator is more efficient.

The Element itself does not provide this functionality.
