Woodstox-based Stax 2 (streaming API for XML) parsing XML

StAX (streaming API for XML) is a stream-oriented pull parsing XML that is fast, resource-intensive, and very suitable for XML files that handle large amounts of data.

Detailed tutorials and instructions can be found in the following articles:

The purpose of this article is to illustrate the StAX2 application in the Woodstox package.
Woodstox official website http://woodstox.codehaus.org/

Download Woodstox-core.jar, the core package has two open source protocols Apache ASL and popular LGPL, while Woodstox-core.jar need Stax2-api.jar support

Stax2 and Stax are somewhat different and incompatible with the original Stax code
