Bug #3842: REXML gives NoMethodError when using parentheses in Xpath sele=
ction criteria
http://redmine.ruby-lang.org/issues/show/3842

Author: Wiebe Cazemier
Status: Open, Priority: Normal
ruby -v: ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux]

When using a selection criterion as follows:

xmldoc.elements.each("descendant::node()[(local-name()=3D'link' or local-=
name()=3D'a') and @rel=3D'sub']")

It gives:

/usr/lib/ruby/1.9.1/rexml/xpath_parser.rb:437:in `expr': undefined method=
 `inject' for true:TrueClass (NoMethodError)

But when leaving out the parentheses around two two local-name functions,=
 it works fine.

It also worked fine on Ruby 1.8.
