[jdom-interest] Which is the faster way ?

[philip.nelson at omniresources.com]

Right now, because getChildren creates another list and because the
implementation is a LinkedList, the getChild approach should be faster.
When getChildren returns the real backing list, I am not sure what the
answer will be, especially now that we are using ArrayList instead of
LinkedList.
