O.K. I had enough of this warning.
/usr/lib/ruby/site_ruby/1.8/rexml/doctype.rb:196: warning: regexp has
`]’ without escape
http://www.ruby-talk.org/blade/84500
/lib/ruby/site_ruby/1.8/rexml/doctype.rb
Original:
source.match(/\s*]\s*>/um, true)
New:
source.match(/\s*]\s*>/um, true)
The warning went away. I hope this is fixed in the next rexml
release.
