[jdom-interest] Setting / Adding Elements "in between"

[ecky at free.fr]

Hi there,

I wonder what is the destined way to insert / replace 
Child Elements of an element. I tried to get the list
of elements (using getMixedContent) add/replace an
element to/of it at the position I like, and try to
use setMixedContent again for the changes to take
effect - which throws an exception for the elements
that were allready present. As I'm working on a lifelist
I imagine the reason why. Then I read in an old mail
of Jason that I just should add the element to the
life list and that's it (see full message at the end
of this mail). This arises my question: Will this not
lead to problems later on, as I don't see how the
parent of the element inserted is being set?

A work around would be to add it to the end and swap
it afterwards to the place I'd like but ... hmmm this
appears to lack some elegance ;-).

Did I get something wrong? In case not, might it be
a good Idea to add a method setXXX( int index, XXX Item )
for each XXX that has to have it's parent set correctly?

I know that the API of Element is already quite large,
but ... hmmm 

Oh, BTW I'm using pre-beta0.7 loaded from CVS on 20.06.2001
I'll try with the latest version as well


cheers
ecky

List kids = element.getParent().getChildren();
kids.add(5, newKid);
// etc

You can use getMixedContent() instead of getChildren() if you want to
worry about comments, entities, and other "node" placements.
