dom4j-xpath-获取xml作为Document.valueOf的字符串

Question

Is there a way to write XPath expression that will be returning xml tree as string when called with Document.valueOf method from dom4j library? I tried /node() , but it returns just texts in all nodes, not including tags.

Answer 1

Method 1 :

String result = document.toXML().toString();

Method 2 : (a more elegant aproach)

DOMSource domSource = new DOMSource(document);

StringWriter writer = new StringWriter();
StreamResult streamResult = new StreamResult(writer);

TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory .newTransformer();
transformer.transform(domSource, streamResult);
String result = writer.toString();
