REXML was inspired by the Electric XML library for Java, which features an easy-to-use API, small size, and speed. Hopefully, REXML, designed with the same philosophy, has these same features. I've tried to keep the API as intuitive as possible, and have followed the Ruby methodology for method naming and code flow, rather than mirroring the Java API.
REXML supports both tree and stream document parsing. Stream parsing is faster (about 1.5 times as fast). However, with stream parsing, you don't get access to features such as XPath.
See the documentation[https://ruby.github.io/rexml/]
We'll start with parsing an XML document
require "rexml/document" file = File.new( "mydoc.xml" ) doc = ::. file
Line 3 creates a new document and parses the supplied file. You can also do the following
require "rexml/document" include # so that we don't have to prefix everything with REXML::... string = <<EOF <mydoc> <someelement attribute="nanoo">Text, text, text</someelement> </mydoc> EOF doc = Document.new string
So parsing a string is just as easy as parsing a file.
After checking out the repo, run
rake test to run the tests.
To install this gem onto your local machine, run
