Here are some hints for creating XML files in java that are compatible with the SuperCollider classes for XML parsing and formatting by Jens Guilden:

• the standard XML header

  <?xml version="1.0" encoding="UTF-8"?>

  causes an error. it can be omitted by setting the OMIT_XML_DECLARATION output property to "yes"
• the parsing fails for big XML files when there are no line feeds, probably due to a maximum line length somewhere. this problem disappears when setting the INDENT output property to "yes"

here's some pseudo-code:

import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
import org.w3c.dom.*;
import org.xml.sax.*;

final DocumentBuilderFactory    builderFactory;
final DocumentBuilder           builder;
final TransformerFactory        transformerFactory;
final Transformer               transformer;
final org.w3c.dom.Document      domDoc;
final DOMSource                 domSrc;
final StreamResult              streamResult;
final Element                   childNode;

builderFactory      = DocumentBuilderFactory.newInstance();
builderFactory.setValidating( true );
transformerFactory  = TransformerFactory.newInstance();
builder             = builderFactory.newDocumentBuilder();
transformer         = transformerFactory.newTransformer();
// builder.setEntityResolver( myResolver );
domDoc              = builder.newDocument();
childNode           = domDoc.createElement( myRootElementName );
domDoc.appendChild( childNode );
myDocument.createSomeXMLCode( domDoc, childNode );
domSrc              = new DOMSource( domDoc );
streamResult        = new StreamResult( myOutputFile );
// note: DTD will be ignored by SuperCollider XML classes, so
// we could use one if we want:
// transformer.setOutputProperty( OutputKeys.DOCTYPE_SYSTEM, myDTD );
transformer.setOutputProperty( OutputKeys.INDENT, "yes" );
transformer.setOutputProperty( OutputKeys.OMIT_XML_DECLARATION, "yes" );
transformer.transform( domSrc, streamResult );
