XML Document to String

What's the simplest way to get the String representation of a XML Document (org.w3c.dom.Document)? That is all nodes will be on a single line.

As an example, from

<root>
  <a>trge</a>
  <b>156</b>
</root>

(this is only a tree representation, in my code it's a org.w3c.dom.Document object, so I can't treat it as a String)

to

"<root> <a>trge</a> <b>156</b> </root>"

Thanks!

First you need to get rid of all newline characters in all your text nodes. Then you can use an identity transform to output your DOM tree. Look at the javadoc for TransformerFactory#newTransformer().

Assuming doc is your instance of org.w3c.dom.Document:

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
StringWriter writer = new StringWriter();
transformer.transform(new DOMSource(doc), new StreamResult(writer));
String output = writer.getBuffer().toString().replaceAll("\n|\r", "");
