Well DOM is a specification which covers many, *many* different
languages. Data typing has to be very generic and most structural
information is expressed in OO jargon.
Sometimes the easiest way serialise something as a DOM is to actually
inherit the DOM::Element class itself. Read and write everything to the
DOM rather than storing stuff in your own OO fields. This option is not
really available to you because you have already written your code.
If you want to learn DOM and XML quickly I'd actually recommend looking
at tutorials in another language that is familiar to you. Something like
perl, python, java or c++ might be ideal.
Occasionally, you might find that XML SAX is a bit easier to use.
