Re: [configuration] union of hierarchical xml configurations in composite configuration

[Oliver Heger]

Unfortunately the configuration API does not provide a simple way to 
construct a union configuration manually. ATM this is done by the inner 
class ConfigurationBuilder of ConfigurationFactory, which creates a 
hierarchical configuration object for all configurations to be united by 
eventually converting them into hierarchical configurations and adding 
their root nodes to a new configuration.

If you have a look at this class, you may get some ideas how to solve 
your problem. Perhaps you can even use this class directly - I didn't 
try this.

I think the API for constructing composite configurations (unions and 
overrides) could be improved in the next version of [configuration].

If I understand the union term correctly, then the following two 
configuration files unioned at foo:

<configuration>
 <foo>
  <bar>0</bar>
  <bar>1</bar>
  <bar>2</bar>
 </foo>
</configuration>
<configuration>
 <foo>
  <bar>1</bar>
  <bar>2</bar>
  <bar>3</bar>
 </foo>
</configuration>
would result in 6 valid keys of foo(0).bar(i).
How can this be achieved programatically with CompositeConfiguration?
