sure. but you really don't need it to solve your task at hand.

it's just the new regexp engine for ruby 1.9 and sometimes i like to
do some stuff with it that the default engine of 1.8 can't do
(zero-width look-behind in this case).

you can still simplify your substitution by using the look-ahead
(which 1.8 *does* understand), so you get rid of the third capture:

  file.gsub(%r{^(<row><entry><text><emph>
face="b">)(.*)(?=<\/emph>)}m) {
    "#{$1}#{$2.gsub(%r{\b\w+\b}) { |w| w.capitalize }}"
  }

cheers
