Is it possible to customize NUnit XML Output

Question

I'm looking at NUnit XML output right now, and wonder if it's possible to generate the output for failures only.

I mean, if a test passes ok, no XML output gets generated for it at all.

(UPDATE: XSLT is not an option here. I don't want XML output for passed tests at all: if I don't need the details about the passed tests, I don't want the system to spend time generating those details.)

The idea is, XML output tend to be quite large if you have a lot of tests, but 80% of the time you're after failures anyway. For such cases, I'd like to run my tests in such a way that only info on failures get generated.

You can specify an XSLT file when you run the NUnit console runner to customise the generated file:

nunit-console /transform:failures.xslt nunit.tests.dll

The default XML file is generated using this XSLT file which can be easily modified to report only failures.

Posted this question to NUnit Google Group, and Charlie Poole confirmed that there's no such option.
