I have a problem. I have a test that needs to assert that one XML document looks
exactly like another XML document.
I couldn''t find a way to compare them as Nokogiri::XML::Documents, so I
converted them both to strings with #to_xml and compared the strings.
Trouble is, sometimes the attributes one of the nodes are rendered into the
string in a different order to the other one, so you get an error of the form:
Diff:
@@ -5,7 +5,7 @@
<Description/>
<Context>
<BackgroundLabels>
- <Label mode="FILTER" name="included"/>
+ <Label name="included" mode="FILTER"/>
</BackgroundLabels>
</Context>
<LookAndFeel nonprofit="false"/>
(RSpec::Expectations::ExpectationNotMetError)
Most annoying.
I''ve seen a couple of RSpec matchers in blog posts that walk and
compare XML fragments but I''m surprised there isn''t something
more concrete that already exists. I feel like I''m missing a way to do
it within an XML library, for example.
Any clues out there?
cheers,
Matt

Aaron Patterson (author of Nokogiri) addressed this issue directly here: http://rubyforge.org/pipermail/nokogiri-talk/2009-April/000258.html I don''t think document comparison was ever implemented in Nokogiri though.

I load my XML docs into a hash using Hash#from_xml and then compare the hashes. On Jan 26, 2011, at 7:26 AM, Matt Wynne <matt at mattwynne.net> wrote:> I have a problem.
