How do I print a groovy Node with namespace preserved?

Question

When I use this code to output some XML I parsed (and modified) with XmlParser

XmlParser parser = new XmlParser()
def root = parser.parseText(fe

I've just had the same problem and after a bit of fiddling I've found a workaround.

You use the XmlSluper instead of the XmlParser and use StreamingMarkupBuilder instead of XmlNodePrinter. Then you take advantage of the closure in bind and use the mkp built-in variable to declare the namespaces.

For example; using the source xml example of Ted's from above:

def root = new XmlSlurper().parseText("http://stackoverflow.com/feeds/question/227447".toURL().text))
def outputBuilder = new StreamingMarkupBuilder()
String result = XmlUtil.serialize(outputBuilder.bind {
    mkp.declareNamespace('':'http://www.w3.org/2005/Atom')
    mkp.declareNamespace('creativeCommons':'http://backend.userland.com/creativeCommonsRssModule')
    mkp.declareNamespace('re':'http://purl.org/atompub/rank/1.0')
    mkp.yield root }
)
println result
