Assuming you want to stick with the standard API...

You could use a <a href="http://java.sun.com/javase/6/docs/api/org/w3c/dom/ls/DOMImplementationLS.html" rel="noreferrer">DOMImplementationLS</a>:

<pre><code>Document document = node.getOwnerDocument();
DOMImplementationLS domImplLS = (DOMImplementationLS) document
 .getImplementation();
LSSerializer serializer = domImplLS.createLSSerializer();
String str = serializer.writeToString(node);
</code></pre>

If the &lt;?xml version="1.0" encoding="UTF-16"?&gt; declaration bothers you, you could use a <a href="http://java.sun.com/javase/6/docs/api/javax/xml/transform/package-summary.html" rel="noreferrer">transformer</a> instead:

<pre><code>TransformerFactory transFactory = TransformerFactory.newInstance();
Transformer transformer = transFactory.newTransformer();
StringWriter buffer = new StringWriter();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
transformer.transform(new DOMSource(node),
 new StreamResult(buffer));
String str = buffer.toString();
</code></pre>

blocks|key|1488205|text|如果您拥有XML的模式，或者可以为其创建JAXB绑定，则可以使用JAXB+Marshaller写入System.out：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1488206|import+javax.xml.bind.*;

If you have the schema of the XML or can otherwise create JAXB bindings for it, you could use the JAXB Marshaller to write to System.out:

<pre><code>import javax.xml.bind.*;
import javax.xml.bind.annotation.*;
import javax.xml.namespace.QName;

@XmlRootElement
public class BoundClass {

 @XmlAttribute
 private String test;

 @XmlElement
 private int x;

 public BoundClass() {}

 public BoundClass(String test) {
 this.test = test;
 }

 public static void main(String[] args) throws Exception {
 JAXBContext jxbc = JAXBContext.newInstance(BoundClass.class);
 Marshaller marshaller = jxbc.createMarshaller();
 marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);
 marshaller.marshal(new JAXBElement(new QName("root"),BoundClass.class,new Main("test")),System.out);
 }
}
</code></pre>

this is what i s done in jcabi:

 StringWriter writer = new StringWriter();
 try {
 Transformer trans = TransformerFactory.newInstance().newTransformer();
 // @checkstyle MultipleStringLiterals (1 line)
 trans.setOutputProperty(OutputKeys.INDENT, "yes");
 trans.setOutputProperty(OutputKeys.VERSION, "1.0");
 if (!(node instanceof Document)) {
 trans.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
 }
 trans.transform(new DOMSource(node), new StreamResult(writer));
 } catch (final TransformerConfigurationException ex) {
 throw new IllegalStateException(ex);
 } catch (final TransformerException ex) {
 throw new IllegalArgumentException(ex);
 }
 return writer.toString();
}
</code></pre>

and it works for me!

With <a href="https://stackoverflow.com/questions/2365208/speeding-up-xpath">VTD-XML</a>, you can pass into the cursor and make a single getElementFragment call to retrieve the segment (as denoted by its offset and length)... Below is an example

<pre><code>import com.ximpleware.*;
public class concatTest{
 public static void main(String s1[]) throws Exception {
 VTDGen vg= new VTDGen();
 String s = "&lt;users&gt;&lt;user&gt;&lt;firstName&gt;some &lt;/firstName&gt;&lt;lastName&gt; one&lt;/lastName&gt;&lt;/user&gt;&lt;/users&gt;";
 vg.setDoc(s.getBytes());
 vg.parse(false);
 VTDNav vn = vg.getNav();
 AutoPilot ap = new AutoPilot(vn);
 ap.selectXPath("/users/user/firstName");
 int i=ap.evalXPath();
 if (i!=1){
 long l= vn.getElementFragment();
 System.out.println(" the segment is "+ vn.toString((int)l,(int)(l&gt;&gt;32)));
 }
 }

I have an <code>org.w3c.dom.Element</code> object passed into my method. I need to see the whole xml string including its child nodes (the whole object graph). I am looking for a method that can convert the <code>Element</code> into an xml format string that I can <code>System.out.println</code> on. Just <code>println()</code> on the 'Element' object won't work because <code>toString()</code> won't output the xml format and won't go through its child node. Is there an easy way without writing my own method to do that? Thanks.

How to I output org.w3c.dom.Element to string format in java?

我将一个org.w3c.dom.Element对象传递到我的方法中。我需要看到整个xml字符串，包括它的子节点(整个对象图)。我正在寻找一种方法，可以将Element转换成我可以System.out.println的xml格式字符串。只对'Element‘对象使用println()是行不通的，因为toString()不会输出xml格式，也不会遍历它的子节点。有没有一种简单的方法，不用写我自己的方法
