Maybe Jimmy should say goodbye to posting on this list??  Please?  Go
make your own list and annoy people there.

Quite probably!

You have a valid point, but then you would because apparently you
designed your product for transaction oriented processing...  This is
not how I use expat and I find it absolutely perfect for my needs. 
What are those needs you ask...  two fold:
  - configuration files
  - code generation

In both cases, I only need one pass through the XML to achieve my
goals... and memory efficiency is way more important to me (in my
embedded systems and designs) than any possible benefit a "compressed
DOM representation" can give me.

Please let it rest and go write some more code for your project and
leave the rest of us in peace to use SAX for what it is best at: 
memory and time efficient XML parsing.
