[jdom-interest] Removing and adding element

[Jason Hunter]

Per the XML spec whitespace counts as content nodes.  Your math seems to 
be ignoring the whitespace text nodes.  If you want to reorder child 
elements, get the child elements as a list -- getChildren() -- and 
manipulate that list -- doing detaches before moves with .detach().
