Right, except that many (most?) object models are navigable in their
own way.

Basically, if your object model *is* the DOM (i.e. if you're using the
document as a document), then use the DOM; if your object model is
something else (i.e. you're using the document as data serialization),
then it is extremely wasteful to build a DOM first, since you'll still 
have to build your own structures in the end.


All the best,


David
