Streaming XML? [was Re: XML Information Set Requirements..]

[Paul Butkiewicz]

Hi Tim.  I did some work with this a few months ago and took the each tick
is a document approach. Unfortunately, I haven't really revisited it much
since.  If you're interested, check out
http://home.earthlink.net/~arabbit/xmlnet  I'm not trying to sell anything
(there was a commercial idea with some friends originally, but, eh. . .),
and you can have the source code if you want.  Just curious, if you wanted
someone to bounce ideas off of, etc.

     This was one of my initial concerns on the DOM - I too will be working
     on ticker-type streams.

     I nearly jumped in early in this conversation to agree with the
     'others' - ie the SAX approach is just as important as DOM and the 2
     should both be of similar (standards) status.

     I held off because I'm new to XML, and I wasn't sure if my alternative
     wasn't too obvious to mention.

     I thought that each tick should be treated as a document. The client
     would have to arrange that each 'document' so received would have to
     be built, and then a document fragment extracted and inserted into a
     client-held document (updating display etc. via DOM events as
     appropriate).

     This approach requires the client of the XML data-source to be aware
     of this of course, which may be a killer for genericity.

     Am I way off base here - and if so, could someone point me to current
     thinking on this issue (I've browsed _a lot_ and seen little/nothing).

     Thanks

     tim

It's not clear that XML supports infinitely long streams (where the
end-tag of the document element is *never* reached).
