I'm using .NET 2.0, and a recent code change has invalidated my previous Assert.AreEqual call (which compared two strings of XML). Only one element of the XML is actually different in the new codebase, so my hope is that a comparison of all the other elements will give me the result I want. The comparison needs to be done programmatically, since it's part of a unit test.
At first, I was considering using a couple instances of XmlDocument. But then I found this: http://drowningintechnicaldebt.com/blogs/scottroycraft/archive/2007/05/06/comparing-xml-files.aspx
It looks like it might work, but I was interested in Stack Overflow feedback in case there's a better way.
I'd like to avoid adding another dependency for this if at all possible.
It really depends on what you want to check as "differences".
Right now, we're using Microsoft XmlDiff: http://msdn.microsoft.com/en-us/library/aa302294.aspx
