Adding an xml-stylesheet Processing Instruction to a document

[jason adam]

I need to set a stylesheet processing instruction to an XML document at the time of creation, before the root tag. I've considered ingesting a "template" xml document that would have the stylesheet and root already defined, but I was wondering if there is a way to do this when the file is actually generated instead.
I've looked through the API and see the ProcessingInstruction interface, as well as the fact that Node has a PROCESSING_INSTRUCTION_NODE field, but I can't seem to figure out how to create a ProcessingInstruction Node and associated to a Document object.
Any pointers to either a tutorial or code example would be great.
Thanks!

Answered my own question... isn't that fun!
Just in case anyone else has the problem, here is my sample code:

            Document myDoc = DocumentBuilderFactory.newInstance().newDocumentBuilder().newDocument();
            ProcessingInstruction pi = myDoc.createProcessingInstruction( "xml-stylesheet" , "type=\"text/xsl\" href=\"MissionSchedule.xsl\"" );
            myDoc.appendChild( pi );
            OutputFormat format = new OutputFormat();
            format.setIndenting( true );
            format.setMethod( "xml" );
            XMLSerializer writer = new XMLSerializer();
            writer.setOutputFormat( format );
            writer.setOutputCharStream( new FileWriter( "D:\\test\\test1.xml" ) );
            writer.serialize( myDoc );
  

Not sure if this is the "correct" way, but it works.
