[xml] What is the advantage of a Reader vs a Parser?

[BJ Chippindale <bchippindale networkAdvantage biz>]

Hello All

I read the code examples and documentation, implemented a reader and I
am implementing a parser, and I STILL have to ask.  It looks as though
the parser and the reader both walk the tree with the reader doing it
more "hands off", and I can't find anything to tell me why/when I should
use one and not the other.  Can anyone point me at something that will
tell me?  ... or am I about to find out as I do the parser? 

respectfully 
BJ
