Remove ?xml version="1.0" encoding="UTF-8"? from XML doc

Question

I have generated an XML file using javax XML transformer. In the XML file thats generated I have the version and the encoding line
<?xml version="1.0" encoding="UTF-8"?>
which is automatically generated in my XML file. Is there any way that I can avoid that from the XML file thats generated.
Here is the transformer that I have used.
public static void printToXML(String fileName){
           try{
                File file = new File(fileName);
                Transformer tr = TransformerFactory.newInstance().newTransformer();
                tr.setOutputProperty(OutputKeys.INDENT, "yes");
                tr.setOutputProperty(OutputKeys.METHOD,"xml");
                tr.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "3");
                tr.transform( new DOMSource(dom),new StreamResult(new FileWriter(file)));
           }catch(TransformerConfigurationException tcex){
                logger.info("TransformerConfigurationException at printToXML method in CSVtoXML.java");
                logger.error("TransformerConfigurationException", tcex);
           }catch(TransformerException tex){
                logger.info("TransformerException at printToXML method in CSVtoXML.java");
                logger.error("TransformerException", tex);
           }catch(IOException ioex){
                logger.info("IOException at printToXML method in CSVtoXML.java");
                logger.error("IOException", ioex);
      }

Answer 1

Well, it is a pretty important line. Why do you need it removed? Anything that really processes XML knows how to read it and determine what encoding was used. That is vital, if you look at the number of questions posted here about foreign language text in XML. If you really have a text processsor that knows how to open a file called something.xml, and knows how to process or ignore most of the pointy bracket things, but not this one, it is time to fix it.
