question: public final String toString ( String codeset ) { StringBuffer retVal = new StringBuffer ( ) ; for ( int i = 0 ; i < prolog . size ( ) ; i ++ ) { ConcreteElement e = ( ConcreteElement ) prolog . elementAt ( i ) ; retVal . append ( e . toString ( getCodeset ( ) ) + "\n" ) ; } if ( content != null ) retVal . append ( content . toString ( getCodeset ( ) ) + "\n" ) ; return versionDecl + retVal . toString ( ) ; }
target:  Override toString so it prints something useful
