Hey Tob
Sorry for the delay in getting back to this one - I've been a bit snowed
under with email here at JavaOne and I nearly missed this message.

You could do it as follows:-
Element parent = currentElement.getParent();
int index = parent.indexOf( currentElement );
List list = parent.content();
list.add( index + 1, element );
Which allows the newElement to be added after the currentElement.

I think there may be too many combinations to deal with - adding at a
specified index, adding after or before a specified sibling node.
Its easy to find the index of something as in the above example code using:-
parent.indexOf(currentElement )
But I am kinda tempted to support adding of a new Element or Text node at a
specified index. So you could do something like this...
Element parent = currentElement.getParent();
int index = parent.indexOf( currentElement );
Element newAfterElement = parent.add( index + 1, "foo" );
Element newBeforeElement = parent.add( index, "foo" );
Would that seem a good idea to people on the list?
