Usage Examples

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
libraries, 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(‘This is the contents’) # Parsed using Ox

MultiXml.parser = :libxml MultiXml.parser = MultiXml::Parsers::Libxml #
Same as above MultiXml.parse(‘This is the contents’) # Parsed
using LibXML

MultiXml.parser = :nokogiri MultiXml.parser = MultiXml::Parsers::Nokogiri #
Same as above MultiXml.parse(‘This is the contents’) # Parsed
using Nokogiri

MultiXml.parser = :rexml MultiXml.parser = MultiXml::Parsers::Rexml # Same
as above MultiXml.parse(‘This is the contents’) # Parsed using
REXML

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 utilize them before attempting to
load any. When loading, libraries are ordered by speed: first Ox, then LibXML,
then Nokogiri, and finally REXML.

Submitting an Issue

We use the GitHub issue tracker to track bugs and features. Before
submitting a bug report or feature request, check to make sure it hasn’t
already been submitted. When submitting a bug report, please include a Gist
that includes a stack trace and any details that may be necessary to reproduce
the bug, including your gem version, Ruby version, and operating system.
Ideally, a bug report should include a pull request with failing specs.

Submitting a Pull Request

Fork the repository.
Create a topic branch.
Add specs for your unimplemented feature or bug fix.
Run bundle exec rake spec. If your specs pass, return to step 3.
Implement your feature or bug fix.
Run bundle exec rake spec. If your specs fail, return to step 5.
Run open coverage/index.html. If your changes are not completely covered by your tests, return to step 3.
Add documentation for your feature or bug fix.
Run bundle exec rake yard. If your changes are not 100% documented, go back to step 8.
Add, commit, and push your changes.
Submit a pull request.

Supported Ruby Versions

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
JRuby

If something doesn’t work on one of these interpreters, it should be considered
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 personally 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.

Inspiration

MultiXML was inspired by MultiJSON.
