JREXML is an add-on for JRuby that uses a Java pull parser library to speed up REXML.
REXML is, unfortunately, painfully slow running under JRuby at the moment due to the slowness of regular expression parsing. JREXML shoves a small wrapper around XPP3/MXP1 (http://www.extreme.indiana.edu/xgws/xsoap/xpp/mxp1/) into the guts of REXML, disabling the regular expression parser and providing close to a 10x speedup.
== Install
Simply install the gem under JRuby:
jruby -S gem install jrexml
And require 'jrexml' to speed up REXML.
gem 'jrexml'
require 'jrexml'
== Source
You can get the JREXML source using Git, in any of the following ways:
git clone git://git.caldersphere.net/jrexml.git
git clone http://git.caldersphere.net/jrexml.git
git clone git://github.com/nicksieger/jrexml.git
You can also download a tarball of the latest JREXML source at http://github.com/nicksieger/jrexml/tree/master.
