See my post about Serializers/Deserializers.
I think that Brett's articles are very good too, but at the implementation side
I would recommend to use Castor from www.exolab.org.
This implementation is very stable and follows the latest Schema recommendation.

I wrote a Serializer/Deserializer for castor objects so you don't need to worry
about validation, DOM nor SAX.
We are using this package (Castor) in production and so far it has been a total
success (cut the dev cost, easy to maintain, ....).
The documentation is also excellent ! And the best part is that this is free !
