String to XML

Question

Hi everyone,
i'm just writing a method, that gets a string and a XPath and want writes the string to the specific XPath in my xml document. The problem ist, that the string itself can contain nodes like (e.g. <image> or something else from my dtd, so i got some problems converting the string to xml. Actually i'm trying this:
     public static void setEditFragment(String content, String xPath) throws Exception {
         DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
         DocumentBuilder builder  = factory.newDocumentBuilder();
         Document document = builder.parse("data.xml");
         XPath xpath = XPathFactory.newInstance().newXPath();
         Node node = (Node)xpath.evaluate(xPath, document, XPathConstants.NODE);
         System.out.println(content);
         node.setTextContent(content);
         // Use a XSLT transformer for writing the new XML file
            Transformer transformer = TransformerFactory.newInstance().newTransformer();
            // Set output to IsoLatin1
            transformer.setOutputProperty(OutputKeys.ENCODING, "ISO-8859-1");
         DOMSource        source = new DOMSource( document );
         FileOutputStream os     = new FileOutputStream("tmp.xml");
         StreamResult     result = new StreamResult( os );
         transformer.transform( source, result ); 
     }but of course this will not work and sets up some cryptic signs in mein xml document....
can anyone give me advice ?
Thanks !

Well, if you already have the data XML encoded, then just write them to a file:
http://java.sun.com/docs/books/tutorial/essential/io/index.html
Make sure you encode the data with UTF8:
http://java.sun.com/javase/6/docs/api/java/lang/String.html#getBytes(java.lang.String)
Write "<?xml version="1.0" encoding="utf-8"?>" before the data!
Note however, I generally don't recommend to write XML data by hand. Rather use a framework like JAXB.
