If I have a custom in-memory tree structure for which
I'd like to provide read-only access through dom4j,
what do I need to provide? From what I can see, I
need to implement the Node interface for each node in
my tree, but as I look at the Node interface, I see
a lot of XPath functionality that could be significant
work to implement beyond just the tree traversal and
introspection functionality that my tree already
has available. I was hoping to be able to put a thin
layer over my tree and make it play in the dom4j
world, but maybe that's unrealistic. Or, maybe I
just haven't found the right info.
Are there any helper classes for doing the XPath
functionality, or perhaps a document that provides
somewhat of a "cookbook" approach?
I'd appreciate any enlightenment that you'd care to
offer! And if this is a case of RTFM! I'd gladly
accept a pointer to the proper "FM". ;-)
