How to handle CDATA character from RSpec in yarjuf xml?

in order to integrate Ruby unittest run via RSpec in Jenkins, I'm using
the yarjuf gem.
This gem can output the RSpec results in JUnit format, in xml file. It all
works, but some of the error message is not parsed correctly.
The reason for that, is that parts of the error message RSpec outputs
contains characters like '<' and '/', and since they can't be outputted to
xml as is, they appears as CDATA.
So this data doesn't appear in the Jenkins JUnit plugin, so I see only
partial error message...
