DOMSerializer Utilities Methods Examples:

In Advanced IO Examples , you saw a glimpse of the DOMSerializer method. This class can serialize any DOM object to a writer or an outputStream. This class is not used at all in Yarfraw's main code base, I downloaded it from the Internet to use for unit tests. You may find it useful when you need to display the elements that are mapped to the 'otherElements' list. 

        DOMSerializer s = new DOMSerializer();
        Document doc = XMLUtils.parseXml("<div xmlns=\"http://www.w3.org/1999/xhtml\">"+
            "<p><i>[Update: The Atom draft is finished.]</i></p>"+
            "</div>", false, true);
        StringWriter w = new StringWriter();
        s.serialize(doc, w);
        Document doc2 = XMLUtils.parseXml(w.toString(), false, true);

You can just as easily write your own serialization code using an XML transformer if you want more controls:

    
    TransformerFactory factory = TransformerFactory.newInstance();
    Transformer trans =  factory.newTransformer();
    Source source = new StreamSource(new StringReader("<div xmlns=\"http://www.w3.org/1999/xhtml\">"+
        "<p><i>[Update: The Atom draft is finished.]</i></p>"+
        "</div>"));
    StringWriter writer = new StringWriter();
    Result result = new StreamResult(writer);
    trans.transform(source, result);

For more details, I encourage to take a look at the Javadoc . Also check out the FAQ section for more insights about this API.
