RE: SAX2: pull interface

I guess that you must being running a plain SAX push parser in a separate thread, and adding ParseEvents to a queue for consumption by the pull client. At least, that's the usual way of adapting push to pull. I must admit that if I needed a pull parser I'd rather have one that could run in a single thread and didn't have the queueing overhead. But that means I'd have to have a state- machine rather than recursive descent based parser. I think that most SAX parsers are RD, so that'd mean new parsers ... and if I needed a new parser I'd probably take the opportunity to design an API that suited the task well rather than trying to bolt it onto SAX. OTOH, once you've got a pull parser it's very easy to construct a push API on top of it and drive it, while(puller.hasNext()) pushClient.handleEvent(puller.getNext()); So maybe we've been doing things back to front ;-) > If someone else is implementing a pull parser, we should > try to agree on a common, parser independent interface. > (e.g. org.xml.pullparser.* ?). I think this would be a useful initiative.
