[jdom-interest] IDREFs

Hi all,
Forgive me if this is a little off-topic but I was wondering how IDREF
attributes are supposed to be handled by parsers. Is it possible to have
a parser that returns the referenced XML element (modulo a call to the
appropriate method) when it encounters an IDREF attribute ? Or is it
left to higher-level applications ? Does JDOM offer such a possibility
and if no, would it make sense to add such a capability ?
Regards,
Chris

I would simply request, but not require, the acknowledgement. The advantages
are:
(1) Provides a loophole for when an acknowledgement isn't possible or
appropriate;
(2) No problems with it invalidating the rest of the license, since you're
following the license whether you comply or not;
(3) You catch more flies with honey than vinegar, or whatever; and
(4) It makes you look more selfless, since you're only requesting credit, not
demanding it.
I think that most developers will be grateful for getting this code for free,
under a license that lets them use it, and will be happy to comply.

Hi,
I've seen several people complaining about the fact that the same root =
node sometimes appears twice in their output. I'm not sure if you need a =
specific configuration for the bug to appear, but I get it when building =
a Document in code (no inputter class) and writing the XML using an =
XMLOutputter. I'm using beta 4 of JDOM.
The problem seems to be in Document.setRootNode. Although the new root =
node is added to the contents as a side effect of settings it as the =
root node, it is never removed from the contents when a new root node is =
specified. In my opinion: since adding the root node is implicit, =
removing it should also be implicit. This would be accomplished by =
changing:=20
// If existing root element, tell it that it's no longer root
if (this.rootElement !=3D null) {
this.rootElement.setIsRootElement(false);
}
to
// If existing root element, tell it that it's no longer root =
and remove it from the node list
if (this.rootElement !=3D null) {
this.rootElement.setIsRootElement(false);
content.remove(this.rootElement);
}
I made this change on my system and it seems to solve the problem in all =
cases I tested.
Would someone with contributing rights please be so kind to consider =
this modification and -if my change is correct- commit it to the CVS =
tree?
Thanks in advance,
puf
