javax.xml.stream.XMLStreamWriter wrapped in a nicer API

object XMLSW {
  private val f = XMLOutputFactory.newInstance

  def document(encoding: String = "utf-8", version: String = "1.0")(body: XMLSW => Unit) = {
    val out = new StringWriter()
    val w = f.createXMLStreamWriter(out)
    val ww = new XMLSW(w)
    ww.document(encoding, version)(body)
    w.flush()
    w.close()
    out.toString
  }
}


class XMLSW(val w: XMLStreamWriter) {
  def document(encoding: String, version: String)(body: XMLSW => Unit) = {
    w.writeStartDocument(encoding, version)
    body(this)
    w.writeEndDocument()
  }

  def element(localName: String, content: String) = {
    w.writeStartElement(localName)
    w.writeCharacters(content)
    w.writeEndElement()
  }

  def element(localName: String, attributes: XMLSW => Unit, content: String) = {
    w.writeStartElement(localName)
    attributes(this)
    w.writeCharacters(content)
    w.writeEndElement()
  }

  def element(localName: String)(body: XMLSW => Unit) = {
    w.writeStartElement(localName)
    body(this)
    w.writeEndElement()
  }

  def attribute(localName: String, value: String) =
    w.writeAttribute(localName, value)
}
