One could of course read in the whole filesystem below the toplevel directory you intend to use, turn it into an XML-structure and then apply XPath rules to it.

Something says me it will not be very efficient ...

    The particular implementation you mentioned, serializing the file system tree into an XML doc then deserializing it into a XML tree, would indeed be inefficient.

    However, XPath can be applied to tree structures (such as a file system) in an efficient manner. It was designed to do just that.

      Thanks. I do some reading up on XPath then (it is several years ago I last used it). I seem to have had the wrong impression that it needed XML to work upon.
