Overview

Aalto
is a toolkit for XML processing. It supports the following features:

1. Namespace aware StAX (Streaming API for XML) compliant (JSR-173) processor
2. Support for both XML parsing and XML creation
3. SAX (Simple API for XML) parsing
4. High performance processor with excellant error handling support

In particular, the main differentiator of Aalto in comparison with other StAX compliant parsers are:

1. Speed of Parsing: Aalto is the fastest java based XML parser available as of date for StAX and SAX based parsing. See jvm-serializers site and this comparative report for further details.
   Hence if parsing speed is critical for your project, then Aalto parser can be a good choice.
2. Non-blocking Asynchronous Parsing: It allows the capability to feed more XML data chunks and incrementally generate more XML events without forcing the current thread to block on I/O read operation
