How to convert a XML file to string ?
How to conver the XML Node to String format ?.
Oh, my XML parser implementation does not have directly to convert as a String. toString() method just returns object information what to do?.
Yes, in this moment, we have to write a our own logic to convert the Node as a String object. Sun Microsystems javax.xml package serves transforming the XML document to String irrespective of the XML parser Implementation(refer JSR 5 and JSR 173 and etc.,)
Even upto individual Node level transformation is possible.
- XML Document to String
- XML element to String
- XML Node to String
Import following package classses apart from your application class import and org.w3c.* package.
import javax.xml.transform.Result;
import javax.xml.transform.Source;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
Write following method and conver simply your Node as String
public static String xmlToString(Node node) {
try {
Source source = new DOMSource(node);
StringWriter stringWriter = new StringWriter();
Result result = new StreamResult(stringWriter);
TransformerFactory factory = TransformerFactory.newInstance();
Transformer transformer = factory.newTransformer();
transformer.transform(source, result);
return stringWriter.getBuffer().toString();
} catch (TransformerConfigurationException e) {
e.printStackTrace();
} catch (TransformerException e) {
e.printStackTrace();
}
return null;
}
Using Oracle implementation, we can do this XMLDocument to String by giving single command.
((XMLDocument)doc).print(System.out);
//any of the output stream , enjoy :)

Nice one - that little sniplet was exactly what I was looking for!
Thanks, this accomplished what I've been looking into for hours!
Thank you! I just wanted to pass a string instead of nodes. Well done.
