Question

In .NET C#, when trying to load a string into xml, you need to use XmlDocument type from System.Xml and do the following:

e.g:

string xmlStr = "<name>Oscar</name>";
XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlStr);
Console.Write(doc.OuterXml);

This seems simple but how can I do this in Java? Is it possible to load a string into xml using something directly, short and simple like above and avoid implementing other methods for this?

Thanks in advance.

Try this:

DocumentBuilderFactory documentBuildFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder doccumentBuilder = documentBuildFactory.newDocumentBuilder();
Document document = 
 doccumentBuilder.parse(new ByteArrayInputStream("<name>Oscar</name>".getBytes()));

You can traverse Oscar by:

String nodeText = document.getChildNodes().item(0).getTextContent() ;         
System.out.println(nodeText);

To transaform back:

TransformerFactory tFactory =  TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
DOMSource domSource = new DOMSource(document);
//to print the string in sysout, System.out
StreamResult streamResult = new StreamResult(System.out);
transformer.transform(domSource, streamResult ); 

To get the result in String:

DOMSource source = new DOMSource(document);
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
StreamResult result = new StreamResult(outStream);
transformer.transform(source, result);
String resultString = new String( outStream.toByteArray());
System.out.println(resultString);
