Re: Reading XML stream using unmanaged c++

The biggest problem with DOM is that it is tree-oriented with each child having a pointer
to its parent. This makes it impossible to create interesting structures such as shared
subtrees. I recently did a truly massive application in XML where we were building
internal hyperlinks to multiple subtrees; this is not possible in DOM. We studied this
problem and the prototype they had built couldn't build the kinds of hyperlinked
structures we needed (the XML ran on a server and we were serving up HTML pages to the
clients). DOM was designed by people who only saw trivial problems. Real problems can't
use it.

I have used the ExPat library to handle XML; the MSXML stuff is rather
complex and if I
recall it is DOM-oriented, which is a really poor design.

I agree with MSXML being complex, but what's wrong with DOM? All the
parsers I've used to date use DOM, and it is great for short XML documents
(the only kind I use).
