In recent releases of Saxon I've been following a similar direction, of making the XPath engine able to work with multiple document representations. The current release includes a JDOM driver to illustrate the principle. I decided to make the interface between the XPath engine and the document representation work at the level of the XPath axes: essentially, the driver has to support a Node object, plus iterators over the 13 XPath axes. This seems to offer a high enough abstraction layer to work efficiently with a wide variety of different stored data structures. Interfacing Saxon to DOM4J shouldn't be at all difficult. The two things that are hard to do are (a) efficently sorting nodes into document order, and (b) implementing the XSLT whitespace stripping rules. Incidentally, some of the things DOM4J and Jaxen are doing look very similar to the original "Java only" Saxon library before it changed direction to become an XSLT engine. Mike Kay
