> This code zip is prototype for SoC 2007 project "Add support for the StAX (JSR-173) cursor API to Xerces-J". The code description is as follows.
> Work underway in Xerces on an implementation of JAXP 1.4. The largest technical change in this new edition of JAXP is the addition of StAX (JSR-173) which introduces XML pull parsing APIs to the Java platform. In constrast to push parsing APIs like SAX, StAX gives control back to the application at each step in the parsing process. The goal of this project is to design and implement the cursor-based XMLStreamReader (and filtering support). It should be possible to accomplish this using XNI by building the XMLStreamReader on top of an XMLPullParserConfiguration.
> The prototype validates the technical mechanism which builds stax parser based on XNI and implements intital XNI-based XMLStreamReader. The work done in the prototype also includes:
> * Use XMLPullConfiguration to simulate stax parsing process.
> * Implement element, attribute, text, namespacecontext, location methods.
> The ongoing work includes:
> * Support filter function.
> * Implement DTD, entity referrence, namespace, etc.
> * Solve the problme that XNI parsing steps do not exactly match the StAX steps. E.g., XNI will treat startDocument xmlDecl as two events, but StAX will treat as one integrated startDocument event.
