ok. well, maybe you could talk to the other developer's and see if they
understand my point - and whether it would be worthwhile to add the
ability to serialize DomDocuent objects. i'm not saying "i'm right you're
wrong" or anything like that, all i want is to make my software as fast as
possible, and i thought serializing would help by avoiding having to
create the "internal tree" again and again.

thanks for the talk.

keep up the good work.
