This is to announce the nux-1.0beta2 release (http://dsd.lbl.gov/nux/).
Nux is a small, straightforward, and surprisingly effective open-source
extension of the XOM XML library.
Features include:
• Seamless W3C XQuery and XPath support for XOM, through Saxon.
• Efficient and flexible pools and factories for XQueries, XSL
Transforms, as well as Builders that validate against various schema
languages, including W3C XML Schemas, DTDs, RELAX NG, Schematron, etc.
• Serialization and deserialization of XOM XML documents to and from
an efficient and compact custom binary XML data format (bnux format),
without loss or change of any information.
• For simple and complex continuous queries and/or transformations
over very large or infinitely long XML input, a convenient streaming
path filter API combines full XQuery support with straightforward
filtering.
• Glue for integration with JAXB and for queries over ill-formed HTML.
• Well documented API. Ships in a jar file that weighs just 60 KB.
Changelog:
XOM serialization and deserialization performance is more than good
enough for most purposes. However, for particularly stringent
performance requirements this release adds "bnux", an option for
lightning-fast binary XML serialization and deserialization.
Contrasting bnux with XOM:
• Serialization speedup: 2-7 (10-35 MB/s vs. 5 MB/s)
• Deserialization speedup: 4-10 (20-50 MB/s vs. 5 MB/s)
• XML data compression factor: 1.5 - 4
