This page shows how to handle XML data returned from the server.
<p />
The form below submits a message to the server and the server
echos it back in XML format.
<br />

<form id="xmlForm" action="xml-echo.jsp" method="post"><div>
Message: <input type="text" name="message" value="Hello XML" />
<input type="submit" value="Echo as XML" />
</div></form>
</div>

</body>
</html>

xml-echo.jsp

<%@page contentType="text/xml" pageEncoding="UTF-8"%>
<%

// !!! IMPORTANT !!! - the server must set the content type to XML
out.print("<root><message>" + request.getParameter("message") + "</message></root>");
%>
