=begin
Percent literal regexp brings SyntaxError with parenthesis. If I use | as separator, then it works fine, but I use () as separator, then it does not work.

 $ ruby -v
 ruby 2.0.0dev (2012-12-23 trunk 38571) [x86_64-darwin11.4.2]
 $ irb
 irb(main):001:0> %r(<telephoneNumber>\(555\)555-5555</telephoneNumber>)
 SyntaxError: (irb):1: unmatched close parenthesis: /<telephoneNumber>\(555)555-5555<\/telephoneNumber>/
