Xhtmldiff is a project mainly written in Ruby, it's free.
Ruby library to see redlines on XHTML
To transform two revisions of an XHTML document into a single valid XHMTL
document with redlines, using the and tags.
run setup.rb:
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install
That's it.
