Then you need the ability to remove a particular child by index too. 
And the ability to remove all children, remove a child by name, remove
all children with a name, add a set of children, remove a set of
children, and so on.

All these things are easily done with the List returned by getChildren()
using standard Java APIs.  I think it's better to give people access to
the List for them to manipulate as they like than reproduce all the List
functionality in Element.
