I can't speak for all people, but the real problem with that code, and
the real reason to use element type names rather than numbers, is that
ordinal-based code is very fragile. It's so fragile that it hardly ever
works. It's so fragile that it seldom even works for your *test
document*. It's so fragile that hardly anyone would do it that way. I'm
sorry I brought up the example!!!!

Full DOM 2+? Maybe.
Core DOM? How is it complex? You have parents, children, elements,
attributes, siblings, etc. Usability enhancements are important (I
typically combine XPath with the DOM whenever I need to do DOM work) but
they are extensions. The DOM itself is not that complicated.
"programmers" (term used lightly). The core concepts can be taught in
five minutes (see the XML Howto). I don't see the complexity. I would
say rather that it isn't complex enough in that it is lacking query
facilities (i.e. XPath).
