Description:
------------
The idea would be that when SELECT * FROM table; is executed on this table:

----------------------------
| id  | name               |
----------------------------
| 1   | User 1             |
| 2   | User 2             |
| 3   | User 3             |
| 4   | User 4             |
----------------------------

Combined with a piece of code like this:

while( $row = mysql_fetch_array($result, RETURN_XML, "UserRecord") ) {
   echo $row["UserRecord"];
}

Would output this:

<UserRecord>
   <id>1</id>
   <name>User 1</name>
</UserRecord>
<UserRecord>
   <id>...etcetera


I do realize this may not be much information to go on, but I am sure the concept is very clear. :)
