A fast XML parser and object serializer that uses only standard C lib. Optimized XML (Ox), as the name implies was written to provide speed optimized XML handling. It was designed to be an alternative to Nokogiri and other Ruby XML parsers for generic XML parsing and as an alternative to Marshal for Object serialization.

fast_xs provides C extensions for escaping text. The original String#fast_xs method is based on the xchar code by Sam Ruby: * http://intertwingly.net/stories/2005/09/28/xchar.rb * http://intertwingly.net/blog/2005/09/28/XML-Cleansing _why also packages an older version with Hpricot (patches submitted). The version here should be compatible with the latest version of Hpricot code. Ruby on Rails will automatically use String#fast_xs from either Hpricot or this gem version with the bundled Builder package. String#fast_xs is an almost exact translation of Sam Ruby's original implementation (String#to_xs), but it does escape """ (which is an optional, but all parsers are able ot handle it. XML::Builder as packaged in Rails 2.0 will be automatically use String#fast_xs instead of String#to_xs available.
