Question

我有一个带有注释节点的Document元素。我尝试使用Transformer对文档进行编组，但注释节点不会被忽略，但在使用JAXB进行编组时，注释节点将被忽略。

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    dbf.setNamespaceAware(true);


    Document doc = null;

    DocumentBuilder db = dbf.newDocumentBuilder();
    Document doc = null;
                   String xmlData="<div>SMITH <span id="first"> dsdsds </span><span id="first"><!- it    ends there --></span>adsadsa</div>";
    doc = db.parse(new ByteArrayInputStream(xmlData.getBytes("UTF-8")));
    DOMSource domSource = new DOMSource(doc.getDocumentElement());
       StringWriter writer = new StringWriter();
       StreamResult result = new StreamResult(writer);
       TransformerFactory tf = TransformerFactory.newInstance();
       Transformer transformer = tf.newTransformer();
       transformer.transform(domSource, result);
       System.out.println("***********DOM PARSING ***************");
       System.out.println(writer.toString());
       System.out.println("***********DOM PARSING ***************");
       Foo foo = new Foo();
       foo.setAny(doc.getDocumentElement());
       System.out.println("***********JAXB MARSHALLING ***************");
       JAXBContext jaxbContext = JAXBContext.newInstance("com.dto");

       Marshaller marshaller = jaxbContext.createMarshaller();
       writer = new StringWriter();
       String itemNamespace="";
        marshaller.marshal(new JAXBElement<Foo>(new QName(
                "", "foo"),
                Foo.class, foo), writer);
       System.out.println(writer.toString());
       System.out.println("***********JAXB MARSHALLING ***************");

Foo对象：

public class Foo {

    @XmlAnyElement(lax = true)
    protected Object any;
/**
     * Gets the value of the any property.
     * 
     * @return
     *     possible object is
     *     {@link Element }
     *     {@link Object }
     *     
     */
    public Object getAny() {
        return any;
    }

输入：

   <div>SMITH <a xmlns:locator="http://ntr.lxnx.org" xmlns="http://www.w3.org/1999/xhtml" id="66ad1d3c-b86c-40a5-994f-fd5e39d80ff6" href="javascript:void(0)" class="lx-anchor lx-annotation-anchor" title="annotation starts here"><img src="/Pages/images/IconNotePadSmall.png" alt="annotation starts here" /></a><span xmlns:locator="http://ntr.lxnx.org" xmlns="http://www.w3.org/1999/xhtml" class="highlighted 66ad1d3c-b86c-40a5-994f-fd5e39d80ff6">v.
