[Opensource] 4.2 Discussion - Configuration Files

[Larry Hamel]

it is a personal preference.  I don't have statistics on what is faster, though expresso config docs are relatively small, so I don't expect DOM to be significantly slower.  I'm willing to be shown otherwise :-)

during debugging, I find that figuring out what method of what class is responsible for a given SAX action is relatively difficult compared to the DOM handling.  with DOM, you read in the whole doc, and if there's some problem with syntax, you get those errors during the read/parse phase.  it seems more clear to me.  after that, taking action based on the DOM tree seems more easily debugged to me too.

again, it is a personal preference, just a memory of former debug sessions, so your mileage may vary.
