Detailed Description

Helper class: DBSXMLHandler.

XML handler class to parse DBS results.

The tricky thing here is that older DBS versions (2.0.5 and
earlier) return results in a different XML format than newer
versions. Previously the result values were returned as attributes
to the `result' element. The new approach returns result values as
contents of named elements.

The old approach is handled directly in startElement(), the new
approach in characters().

NOTE: All results are returned in the form of string values of
      course!

Make sure that all results arrays have equal length.

We should have received complete rows from DBS. I.e. all
results arrays in the handler should be of equal length.
