XOM API for Processing XML with Java

["Hallvard Tr�tteberg" <hal AT idi.ntnu.no>]

Hi,

As mentioned in a previous posting, I'm trying to reimplement several JDOM
sub-classes as subclasses of corresponding XOM-classes. Two of these efforts
rely on tracking changes in the parent / child relationsship, to keep track
of all IDs in a document and to notify listeners of changes in general.

The Element.checkAttribute and Attribute.checkType and Attribute.checkValue
can be used for this purpose at the attribute level. However, I haven't
found a way of doing this at the TreeNode/Element level. In particular, the
Element class makes the TreeNode.insertChild(int position, Node node) final
so I cannot hook into the child insertion process by subclassing Element! I
cannot utilise setParent either (as I did for JDOM) since it is package
private.

I suggest adding a TreeNode.checkChild(Node node) or
Element.checkChildElement(Element e) to make such tracking possible in
general.
