The Virtual Machine is actually a runtime for the Scheme r5rs language. Unfortunately, there are no Scheme implementations written in PHP. Writing one is easy enough (2 weeks), but anyway it requires time. As for the requirements draft, don't miss ordpath: http://www.cs.umb.edu/~poneil/ordpath.pdf Hi Thomas,

I've exactly the problem you described and I'm asking myself, if it makes sense, to implement XPath for this component or to reduce the functionality to some methods like: $tree->getPath( $node1, $node2 ); This method resolves my current problems, but I'm sure, that there will come also other questions I want to ask to the tree.
