module Ox

Description: ↑

Ox handles XML documents in two ways. It is a generic XML parser and writer as well as a fast Object / XML marshaller. Ox was written for speed as a replacement for Nokogiri and for Marshal.

As an XML parser it is 2 or more times faster than Nokogiri and as a generic XML writer it is 14 times faster than Nokogiri. Of course different files may result in slightly different times.

As an Object serializer Ox is 4 times faster than the standard Ruby Marshal.dump(). Ox is 3 times faster than Marshal.load().

Object Dump Sample: ↑

require 'ox'

class Sample
  attr_accessor :a, :b, :c

  def initialize(a, b, c)
    @a = a
    @b = b
    @c = c
  end
end

# Create Object
obj = Sample.new(1, "bee", ['x', :y, 7.0])
# Now dump the Object to an XML String.
xml = Ox.dump(obj)
# Convert the object back into a Sample Object.
obj2 = Ox.parse_obj(xml)

Generic XML Writing and Parsing: ↑

require 'ox'

doc = Ox::Document.new(:version => '1.0')

top = Ox::Element.new('top')
top[:name] = 'sample'
doc << top

mid = Ox::Element.new('middle')
mid[:name] = 'second'
top << mid

bot = Ox::Element.new('bottom')
bot[:name] = 'third'
mid << bot

xml = Ox.dump(doc)
puts xml
doc2 = Ox.parse(xml)
puts "Same? #{doc == doc2}"

ox_default_options() → Hash click to toggle source

Returns the default load and dump options as a Hash. The options are

  • indent: [Fixnum] number of spaces to indent each element in an XML document

  • trace: [Fixnum] trace level where 0 is silent

  • encoding: [String] character encoding for the XML file

  • with_dtd: [true|false|nil] include DTD in the dump

  • with_instruct: [true|false|nil] include instructions in the dump

  • with_xml: [true|false|nil] include XML prolog in the dump

  • circular: [true|false|nil] support circular references while dumping

  • xsd_date: [true|false|nil] use XSD date format instead of decimal format

  • mode: [:object|:generic|:limited|nil] load method to use for XML

  • effort: [:strict|:tolerant|:auto_define] set the tolerance level for loading

  • symbolize_keys: [true|false|nil] symbolize element attribute keys or leave as Strings

  • skip: [:skip_none|:skip_return|:skip_white] determines how to handle white space in text

  • smart: [true|false|nil] flag indicating the SAX parser uses hints if available (use with html)

  • convert_special: [true|false|nil] flag indicating special characters like &lt; are converted with the SAX parser

  • invalid_replace: [nil|String] replacement string for invalid XML characters on dump. nil indicates include anyway as hex. A string, limited to 10 characters will replace the invalid character with the replace.

  • strip_namespace: [String|true|false] false or “” results in no namespace stripping. A string of “*” or true will strip all namespaces. Any other non-empty string indicates that matching namespaces will be stripped.

@return [Hash] all current option settings.

Note that an indent of less than zero will result in a tight one line output unless the text in the XML fields contain new line characters.

parse_obj(xml) → Object click to toggle source

Parses an XML document String that is in the object format and returns an Object of the type represented by the XML. This function expects an optimized XML formated String. For other formats use the more generic ::load method. Raises an exception if the XML is malformed or the classes specified in the file are not valid. @param [String] xml XML String in optimized Object format. @return [Object] deserialized Object.

sax_parse(handler, io, options) click to toggle source

Default (skip nothing) @param [nil|String|true|false] :strip_namespace “” or false result in no namespace stripping. A string of “*” or true will strip all namespaces. Any other non-empty string indicates that matching namespaces will be stripped.
