I'm writing an application using the Java binding of DOM (Xerces,
specifically),
but I'm trying to use the JAXP framework and generic DOM interfaces/methods
as much as possible to avoid tying myself permanently to a specific DOM
implementation.
What I was trying to determine was whether there is a way to "destroy" a
Node
(or even a complete Document) after having created it. My application is
doing
multiple transforms and basically handing off one Document (or Node
sub-tree)
from one Transformer to the next. As I go through several transformations,
I'd
like to get rid of the Transformed subtrees as I go.
My current design "hands off" a node from one Transform to the next and
currently each of the nodes are children of the same document. Once I
complete
a transformation, its "source Node" will no longer be needed as I go down a
chain of Transforms. I know you can do a "removeChild" to remove a Node
from wherever it was inserted into the tree, but there still seems to be an
association to the owner document. Is there a way to "break" that
association
so that once the Node is no longer needed, all references to it can be
deleted
so that it will be garbage collected?
I want to try to avoid any XML Parser/DOM Implementation-specific calls if
at
all possible.
