Updating XML - how to convert an arraylist back to a node

[John Dowling]

See code below; when i parse xmlInput on line 2 an arraylist appears to be returned for program. How do i convert this back to a node suitable for XmlNodePrinter? Can this be done with MarkupBuilder? Thanks


def xmlInput = parser.parse (new FileInputStream(INPUT_XML))
def program = xmlInput["md:programs"]["md:program"]

writer = new StringWriter()
new XmlNodePrinter(new PrintWriter(writer)).print(program)
println (writer.toString())
