Org.w3c.dom.Document to XML string using Groovy

Question

I have an instance of org.w3c.dom.Document that I need to convert to an XML string. I know how to do this in Java (using the features of javax.xml.transform), but I wondered if there is a “groovy” way to do this?

I tried using the DomToGroovy class, which successfully creates a version of the groovy script DOM document. But I'm not sure how to use this to create an XML string. I could bark the wrong tree ...

Any help would be greatly appreciated!
