Extract method
Use the public void extract(String xpath) throws DESPIException to retrieve individual field values from backend object representation.
Purpose
This method needs implementation only if an Xpath expression can be used to retrieve individual field values from backend object representation. This method is invoked after getNext() is called with boolean value as false.
The method should first extract the value from backend object representation defined through Xpath and use OutputCursor and OutputAccessor interfaces to populate values in runtime data structure.
