It all depends on what you want to do with the data, but in general I would want to store all data and also make sure that the semantics interpreted by the MUA are preserved in the db, so for example:

I have heard using PDB files can help diagnose where a crash occurred.

First, i suggest you to use the `object` html tag which is standardized, `embed` is not.

Well, if you listed your error codes, it might help. Off the top of my head, do you have something in Particles.h to make sure that the file is only included once?

Not sure what type of processing you're doing, but for very large XML, I've always been a fan of event-based processing. Maybe it's my Java background, but I really do like SAX. You need to do your own state management, but once you get past that, it's a very efficient method of parsing XML.
