Re: Best way to read an XML properties file?

  This does not answer your question, but I have developed a
  special notation for complex properties and now would like to
  take this opportunity to advertise this notation and a GPL
  library implementing it.

  For simple cases, my DOM implements the Map and List interface:

roomFrom( "< a=b c=d x y z >" ).get( "a" )

  gives ?b?, and

roomFrom( "< a=b c=d x y z >" ).get( 0 )

  gives ?x?, assuming a preceding

import static de.dclj.ram.notation.unotal.RoomFromModule.roomFrom;

  A java.io.File can be used instead of a string
  so as to read the configuration from a file.

  A slightly more complex example:

public class Main
{ public static void main( final java.lang.String[] args )
  {
    final de.dclj.ram.notation.unotal.RoomSource room =
    de.dclj.ram.notation.unotal.RoomFromModule.roomFrom
    (
      " " +
      " < < &car " +
      " Chevy=< doors=4 paint=green > " +
      " Ford=< doors=2 paint=purple > " +
      " Nissan=< doors=3 paint=red >> " +
      " < &bike " +
      " < inch=26 &green > " +
      " < inch=27 &purple >>> " +
      " " );

    java.lang.System.out.println
    ( room.getRoom( 0 ).getRoom( "Ford" ).get( "doors" ));

    java.lang.System.out.println
    ( room.getRoom( 0 ).getType() );

    java.lang.System.out.println
    ( room.getRoom( 1 ).hasType( "bike" ));

    for( final java.lang.Object o : room.getRoom( 1 ))
    java.lang.System.out.println( o ); }}

car
true
< &green inch =26 >
< &purple inch =27 >

  Disclaimer: The recent jar contains some debug code and is
  experimental. If someone would want to use this, I can provide
  a jar without the debug code and some support.
