Question

Update There is no ready XML parser in Java community which can do NIO and XML parsing. This is the closest I found, and it’s incomplete: http://wiki.fasterxml.com/AaltoHome

I have the following code:

InputStream input = ...;
XMLInputFactory xmlInputFactory = XMLInputFactory.newInstance();

XMLStreamReader streamReader = xmlInputFactory.createXMLStreamReader(input, "UTF-8");

Question is, why does the method #createXMLStreamReader() expects to have an entire XML document in the input stream? Why is it called a “stream reader”, if it can’t seem to process a portion of XML data? For example, if I feed:

<root>
    <child>

to it, it would tell me I’m missing the closing tags. Even before I begin iterating the stream reader itself. I suspect that I just don’t know how to use a XMLStreamReader properly. I should be able to supply it with data by pieces, right? I need it because I’m processing a XML stream coming in from network socket, and don’t want to load the whole source text into memory.

Thank you for help,
Yuri.

If you absolutely need NIO with content “push”, there are developers interested in completing API for Aalto. Parser itself is complete Stax implementation as well as alternative “push input” (feeding input instead of using InputStream). So you might instead want to check out mailing lists if you are interested. Not everyone reads StackOverflow questions. 🙂
