A generic swappable back-end for XML parsing

gem install multi_xml

https://rdoc.info/gems/multi_xml

require 'multi_xml'
MultiXml.parser = :ox
MultiXml.parser = MultiXml::Parsers::Ox # Same as above
MultiXml.parse('<tag>This is the contents</tag>') # Parsed using Ox
MultiXml.parser = :libxml
MultiXml.parser = MultiXml::Parsers::Libxml # Same as above
MultiXml.parse('<tag>This is the contents</tag>') # Parsed using LibXML
MultiXml.parser = :nokogiri
MultiXml.parser = MultiXml::Parsers::Nokogiri # Same as above
MultiXml.parse('<tag>This is the contents</tag>') # Parsed using Nokogiri
MultiXml.parser = :rexml
MultiXml.parser = MultiXml::Parsers::Rexml # Same as above
MultiXml.parse('<tag>This is the contents</tag>') # Parsed using REXML
MultiXml.parser = :oga
MultiXml.parser = MultiXml::Parsers::Oga # Same as above
MultiXml.parse('<tag>This is the contents</tag>') # Parsed using Oga

The parser setter takes either a symbol or a class (to allow for custom XML parsers) that responds to .parse at the class level.

MultiXML tries to have intelligent defaulting. That is, if you have any of the supported parsers already loaded, it will use them before attempting to load a new one. When loading, libraries are ordered by speed: first Ox, then LibXML, then Nokogiri, and finally REXML.

This library aims to support and is tested against the following Ruby implementations:

• 3.2
• 3.3
• 3.4
• JRuby 10

If something doesn't work on one of these versions, it's a bug.

This library may inadvertently work (or seem to work) on other Ruby implementations, however support will only be provided for the versions listed above.

If you would like this library to support another Ruby version, you may volunteer to be a maintainer. Being a maintainer entails making sure all tests run and pass on that implementation. When something breaks on your implementation, you will be responsible for providing patches in a timely fashion. If critical issues for a particular implementation exist at the time of a major release, support for that Ruby version may be dropped.

MultiXML was inspired by MultiJSON.
