Evaluating XPath expressions without loading the DOM tree in thememory

[Luc Mercier]

Hi folks,

I'm using dom4j to process xml, and mostly do some stuff like that:

Document xmldoc = ...
for (Object o : xml.selectNodes("an xpath expression")) {
Node n = (Node) o;
// do some stuff
}


The stuff I need to do internally only requires access to the subtree
rooted in the node 'n', which is rather small, but the whole document is
huge.

I would like to be able to do something similar with documents I cannot
load into memory. Therefore what I would like to have is an
implementation of Document which, instead of being an explicit tree, is
an implicit representation of a document stored in a file.

As I understand, dom4j does not allow to do that. Writing a new
implementation of Document seems a lot of work, and I'm not really
considering this option.

Any suggestion?

- Luc.
