I used the transformer code mentioned in below link to convert xml element and its child to xml string

How to convert xml Element and its child nodes into String in Java?

The problem is i am seeing some weird characters , only first element text content is in plain text rest is some weird encoding

For quick reference here is the code 

Transformer transformer = TransformerFactory.newInstance().newTransformer(); transformer.setOutputProperty(OutputKeys.INDENT, "yes");  
StreamResult result = new StreamResult(new StringWriter()); 
DOMSource source = new DOMSource(node);
transformer.transform(source, result);
String xmlString = result.getWriter().toString(); System.out.println(xmlString);

Input looks like below

Try adding an XML declaration which specifies the encoding of your XML file (UTF-8 in the example). Maybe it helps :)

<?xml encoding="UTF-8"?>

Look at: DOMImplementationLS serialize to String in UTF-8 in Java

Notice this piece:

StringWriter output = new StringWriter();

and:

String xml = output.toString();

The example above is calling toString on the string writer, you're calling it on the streamResult.

Trying breaking it out like that example does and see if that works for you.
