Hello all,

my application is in need of a document-wide unique node-id for every node
in a DOM tree. These ids should be persistent, i.e., uniquely exist as long
as the document existst and not as long as the identified node exists.

I was wondering if an implementation class of Xerces provides such a
feature? After a look at the API I only found int NodeImpl.getNodeNumber().
Is the returned number an id or is it, e.g., a position? (I wasn't able to
find anything about it)

Otherwise, does the possibility exist to write a wrapper class around
NodeImpl and configure Xerces so that it instantiates the wrapper instead of
NodeImpl?

Kind regards,
Martin Bernauer
