PathTracker

public class PathTracker (Code)

Maintains the current Path as a stream is moved through.

Can be linked to a HierarchicalStreamWriter or HierarchicalStreamReader by wrapping them with a PathTrackingWriter or PathTrackingReader.

Example

 PathTracker tracker = new PathTracker();
 tracker.pushElement("table");
 tracker.pushElement("tr");
 tracker.pushElement("td");
 tracker.pushElement("form");
 tracker.popElement("form");
 tracker.popElement("td");
 tracker.pushElement("td");
 tracker.pushElement("div");
 Path path = tracker.getPath(); // returns "/table/tr/td[2]/div"
