Re: DESIGN PROPOSAL: Java XMLIterator


software design proposal
Oops.  I forgot the "access" property of the flat interface...

| Iterator {
|    Node next();
| }
| 
| Node {
|   Type     type();     // Text, Element, Comment, PI
|   Iterator children(); // Only works for elements
|   String   value();    // Returns value as defined by DOM.
|   String   name();     
    Access   access();   // Returns the node's current accessability,
                         // this can be:
                         // RANDOM:
                         //  The children() and value()
                         //  functions may be called
                         //  as many times as necessary.
                         // SEQUENTIAL:
                         //  The children() or value()
                         //  function may be called
                         //  exactly once.  After the
                         //  call, the access level
                         //  drops to inaccessable.
                         // INACCESSABLE:
                         //  The children() and value()
                         //  functions will throw the
                         //  NotAccessable exception
                         //  if they are called.
| };
|         
| The only "catch" with this interface, is that particular
| functions may throw the NotAccessable() error when their
| content has been skipped and the iterator is over a 
| sequential access medium.   Once you get use to this
| paradigm the nested iterator becomes very simple, 
| intutitive, and it blends in nicely with XSLT node-sets, etc.  
| 
| The above interface is very similar to the "C" call
| level interface for YAML and I've been using a Python
| equivalent for some time with great success.
| 
| Best,
