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.
In the spirit of free software , everyone is encouraged to help improve this project.

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.
bundle exec rake spec. If your specs pass, return to step 3.
- Implement your feature or bug fix.
bundle exec rake spec. If your specs fail, return to step 5.
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.
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
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.
MultiXML was inspired by MultiJSON.
