could any one tell me how to output the xml data in the following format.Thanks

Have you sent a Content-type header?
This is required in order to signal to the user agent that the document is of an XML type and should be parsed as such.

PHP Code:

---

header('Content-type: text/xml; charset=utf-8');

Also, you should never use echo() to output large chunks of content like that. In fact there is simply no need to use any PHP here.
