Hi,

I'm new to this list, so I apologize if this is the wrong place to post
this
message. If it is the wrong place, then could you please tell me where I
should be asking these questions?

I'm trying to get Xalan-J to work with a Persistent DOM. As such, all the
nodes of the DOM are not in memory at the same time and are only
loaded when required. In my DOM implementation, no references
are kept to the node so the Java GC can remove un-referenced
nodes.

When I run the DOM thought Xalan the nodes to not get GC and I think
this is due to the DTM module maintaining references to the nodes.
Also, it appears to go though the DOM serially (does this sound right).

My questions are...

1. If there a way to replace DTM in a DOM by DOM basis (i.e. for a
normal XML document the normal DTM is used) and for my DOM
I can use my own implementation without modifying the Xalan source
code.

2. Can you point me at any information of implementing my own
DTM interface (other that the source code).

3. Do you think this is a pointless exercise and should I try
another processor (I'd rather not)?

Thanks for you help.
