How to remove the ?xml declaration.

Question

Hi,
We are processing a large ASCII input file and converting it into XML. When we do it on a single go, the JVM crashes due to out of memory error.
We tried to write the XML output for a group of input lines into the file and start processing the next set. We get the <?xml> declarative tag every time we write to the file. How can we remove this?
Thanks in advance.

This is how I managed to do it. The latest xerces.xml.serializer package claims to do it as well for various sgml (html/xml etc) but the help is incomplete and I can find nothing on the internet to do this. Historically (ie a year ago) I've seen code such as XMLSerializer s = new XMLSerializer(Properties properties); s.serialize()... But this has been deprecated.
It seems a great shame to me that Microsoft is running away with decent usable implementations of the DOMDocument standards.
   * Serializes the given document to the writer, optionally omitting the xml declaration
   * @param source
   * @param output
   * @throws XMLException
  public static void transform(Document source, Result output, boolean omitXmlDeclaration)
      throws XMLException
    try {
      if (output == null) {
        throw new IllegalArgumentException("Output result stream cannot be null");
      if (source == null) {
        throw new IllegalArgumentException("Source document cannot be null");
      Transformer transformer = TransformerFactory.newInstance().newTransformer();
      transformer.setOutputProperty("omit-xml-declaration", omitXmlDeclaration ? "yes" : "no");
      transformer.transform(new DOMSource(source), output);
    catch (Exception e) {
      Log.error("Error in transform", e);
      throw new XMLException(e);
  }
