Is there a Push-based/Non-blocking XML Parser for Java?
java, nonblocking, xml
Solution
This is a (April 2009) post from the Xerces J-Users mailing list, where the original poster is having the exact same issue. One potentially very good response by "Jeff" is given, but there is no follow up to the original poster's response:

It's potentially new enough to bump on the list, or at very least help with the search.
Edit
Found another useful link, mentioning a library called Woodstox and describing the state of Stream vs. NIO based parsers and some possible approaches to emulating a stream:

Problem
I'm looking for an XML parser that instead of parsing from an InputStream or InputSource will instead allow blocks of text to be pushed into the parser. E.g. I would like to have something like the following: ``` public class DataReceiver { private SAXParser parser = //... private DefaultHandler handler = //... /** * Called each time some data is received. */ public void onDataReceived(byte[] data) { parser.push(data, handler); } } ``` The reason is that I would like something that will play nice with the NIO networking libraries rather than having to revert back to a thread per connection model required to support a blocking InputStream.
