Create XML document on GWT client side

I'm trying to create some XML files on the client and then send them to the server (nothing special, just something like <root><blabla>...</blabla>...</root>).

Doing this by hand would be possible but extremely inflexible and I see myself making a lot of mistakes. So I was looking for a XML generator in GWT and found the "com.google.gwt.xml.client" Package. Sadly I cant find examples how to create XML documents with it. Can anybody provide me an example (or linke ot an examle)?

Best regards, Stefan

Accepted answer is right, but there is a little mistake on it, node1 and node2 should be linked to root, not to doc.

So this line:

doc.appendChild(node1);

should really be:

root.appendChild(node1);

Well ok, your anser works but some things to append.

First you have to include 

<inherits name="com.google.gwt.xml.XML" />

in your *gwt.xml file (http://blog.elitecoderz.net/gwt-and-xml-first-steps-with-comgooglegwtxmlerste-schritte-mit-gwt-und-xml-unter-comgooglegwtxml/2009/05/ )

second you use the following namespaces: 

import com.google.gwt.xml.client.Document;
import com.google.gwt.xml.client.Element;
import com.google.gwt.xml.client.XMLParser;

Here is an example. To generate the following xml :

<root>
  <node1 attribute="test">
     my value
  </node1>
  <node2 attribute="anothertest"/>
</root>

You have to write the following code on the Java client side :

import com.google.gwt.xml.client.Document;
import com.google.gwt.xml.client.Element;
import com.google.gwt.xml.client.XMLParser;

public static void main(String[] args) {
    Document doc = XMLParser.createDocument();

    Element root = doc.createElement("root");
    doc.appendChild(root);

    Element node1 = doc.createElement("node1");
    node1.setAttribute("attribute","test");
    node1.appendChild(doc.createTextNode("my value"));
    doc.appendChild(node1);

    Element node2 = doc.createElement("node2");
    node2.setAttribute("attribute","anothertest");
    doc.appendChild(node2);

    System.out.println(doc.toString());
}
