=begin
The attached file: rexml_test.rb was written in the context of a rails app, and used ./script/runner to execute.

It uses Nokogiri by way of comparison to REXML.

There are 4 test cases, and only the last one fails: REXML trying to parse the contents of A > B
It turns out, surprisingly, that the line is required for this to fail - without it, all tests will work.

% gem list nokogiri

HI. You're using libxml2 version 2.6.16 which is over 4 years old and has
plenty of bugs. We suggest that for maximum HTML/XML parsing pleasure, you
upgrade your version of libxml2 and re-install nokogiri. If you like using
libxml2 version 2.6.16, but don't like this warning, please define the constant
I_KNOW_I_AM_USING_AN_OLD_AND_BUGGY_VERSION_OF_LIBXML2 before requring nokogiri.

Can you try with a script that runs outside rails?

The script you've attached doesn't work. I modified it to what I think it should be, but nothing breaks on 1.8.7 or 1.8.6. I've attached the test script I used.
