Description
The functx:path-to-node-with-pos function returns a path to that node, starting with the root element. Specifically, it will concatenate all the names of its ancestors, using a forward slash as a separator. If an element with that name appears more than once in a parent, a predicate is included to indicate the sequence number of that particular node.
