How to write xml dom to string or file

[Daniel63656]

Having written a simple xml example using the xmlWriter, how to write the dom to string or file?

 val xmlWriter = xmlStreaming.newWriter()

        xmlWriter.apply {
            startDocument("3.1", "utf-8", true)
            startTag(null, "root", null)
            attribute(null, "id", null, "123")

            startTag(null, "child", null)
            attribute(null, "name", null, "John Doe")
            text("This is a child node")
            endTag(null, "child", null)

            endTag(null, "root", null)
            endDocument()
        }

Basically you want a newWriter instance that takes an Appendable parameter. For files there is the ability to specify the Writer as output.
