If Perl is part of your bag of tricks, you might want to have a look at
the XML::SemanticDiff module[1]. It provides any easy way to compare XML
instances while ignoring insignificant whitespace differences and doing
the Right Thing(tm) with regard to XML Namespaces (elements
<foo:element/> <bar:element/> and <element/> are counted as equivalent
as long as they are bound to the same namespace and are otherwise

As a bonus, the implementation is built upon a simple event-handler
mechanism that offers an easy way to add side effects to the 'diff-ing'
process (insert/update data to databases, widget callbacks, etc.).
