Question

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

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());
}
