First of a couple of pointers.

* Indent two spaces. That is the Ruby common practice and will make
your code easier to read. (If don't like such shallow indention then
use 4, but please 8 is just too much).
* Post large samples like this to snippets sites such as github's gist
(http://gist.github.com/) it will colorize the output nicely, again
making it easier to read.
* Add some comments to the code to explain what is going on. People
not familiar with libxml-ruby might be able to help if they knew how
XML::Reader worked.

Having said that, you might get better performance if you eliminate
where the two documents are the same, then what is left over will be
their differences. Just a thought.
