A generic swappable back-end for XML parsing
gem install multi_xml
Lots of Ruby libraries utilize XML parsing in some form, and everyone has their
favorite XML library. In order to best support multiple XML parsers and
multi_xml is a general-purpose swappable XML backend library. You
use it like so:
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
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 utilize them before attempting to load any. 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:
- Ruby 1.8.7
- Ruby 1.9.2
- Ruby 1.9.3
- Ruby 2.0.0
- Ruby 2.1.0
If something doesn't work on one of these interpreters, 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.
