> I do have one question though. I currently use XPath to navigate a Java
> Bean object graph, where each object implements a Map. However, I now need
> to be able to calculate the interdependencies between different expressions
> against an object graph.

>
>
> For example, in the case of the path:

>
>
> /foo/bar/tomorrow = 1 and /foo/two/three = 0
>
>
>
> I would, ideally, like to be able to be able to make a call that returns
> the object for each axis of each expression. And so would return an array
> of Pointers for: [ foo, bar, tomorrow, two, three]

> However, I suspect there is no utility class to do this, and was hoping I
> could gain access to the parse tree for an expression and then walk each
> axis of each path myself. However, I cannot see a way of doing this either,
