[Groovy] Class StaxBuilder

class StaxBuilder
extends BuilderSupport

A Groovy builder that works with Stax processors. A typical usage is as follows:

 import javax.xml.stream.XMLOutputFactory
 def factory = XMLOutputFactory.newInstance()
 def writer = new StringWriter()
 def builder = new groovy.xml.StaxBuilder(factory.createXMLStreamWriter(writer))
 builder.root1(a:5, b:7) {
     elem1('hello1')
     elem2('hello2')
     elem3(x:7)
 }
 assert writer.toString() == 'hello1hello2'
 

 @Grab('org.codehaus.jettison:jettison:1.2')
 import org.codehaus.jettison.mapped.*
 import javax.xml.stream.XMLStreamException

 def conv = new MappedNamespaceConvention()
 def writer = new StringWriter()
 def mappedWriter = new MappedXMLStreamWriter(conv, writer)
 def builder = new groovy.xml.StaxBuilder(mappedWriter)
 builder.root1(a:5, b:7) {
     elem1('hello1')
     elem2('hello2')
     elem3(x:7)
 }
 assert writer.toString() == '''{"root1":{"@a":"5","@b":"7","elem1":"hello1","elem2":"hello2","elem3":{"@x":"7"}}}'''
