[Digester] Parse into HashMap using Commons Digester

[Sudhi Shetty <re...@gmail.com>]

I need to parse a XML file having the following format(Not posting the
actual XML due to confidentiality reasons but repesenting the problem
in a sample format) :

<movielibraries>
<library name="Libra">
  <movie name="XYZ">
       <releasedate date="ABC"/>
       <director name="SDR"/>
   </movie>
</library>
<library>
......
</library>
</movielibraries>

I want to parse this into a HashMap where in the 'key' is the library
name and value is 'List' of Movie instances for that library.
class Movie {
   String name;
   Date releaseDate;
   String director
}
Is it possible to achieve this using Digester?

Just push the HashMap on the stack before calling parse(). For <library> 
I would probably define my own rule, which would put an empty 
ArrayList<Movie> with the name of library as key into that hashmap. 
Constructing the Movies and adding them to the list should be quit 
simple then.
