What is the best way of testing XML responses?

Question

I'm using selenium IDE to test my webpages but unfortunately I cannot use it to test those pages that return an xml response. Some people use Selenium Remote Control, others use Pearl modules like WWW::Mechanize and Test::XML or Test::XPath (but these are no option for me since I use Java).

What is the best way to test the XML responses?

Answer 1

You can use XMLUnit to compare the response against an expected value. If direct comparison isn't desirable, you can filter the response first, e.g. an XSLT transform, to produce something that is more easily tested.
