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 libraries, multi_xml is a general-purpose swappable XML backend library. You use it like so:
require 'multi_xml' 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
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 LibXML, then Nokogiri, then REXML.
In the spirit of free software, everyone is encouraged to help improve this project.
