Hi all,

does anybody knows how to convert an org.w3c.dom.Document into a String ?? (basically I want to log the dom tree into a string object not a file). Thanks

You can use the javax.xml.transform package.
Its fairly self-explanatory :

// To transform the Document to a stream
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

....

Document doc ...

TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer();
DOMSource source = new DOMSource(doc);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
StreamResult result = new StreamResult(baos);
transformer.transform(source, result);

String docString = new String(baos.toByteArray());

This code throws a bunch of exceptions, so you'll need to add in error handling etc.

P.S.: Just to be a fisherman, google for org.w3c.dom.Document "to String"
