You can use mysqldump utility to retrieve schema in XML

There are three general ways to invoke mysqldump:
shell> mysqldump [options] db_name [tables]
shell> mysqldump [options] --databases DB1 [DB2 DB3...]
shell> mysqldump [options] --all-databases --xml, -X Write dump output as well-formed XML.

--password[=password], -p[password] The password to use when connecting to the server. If you use the short option form (-p), you cannot have a space between the option and the password. If you omit the password value following the --password or -p option on the command line, you are prompted for one.
--user=user_name, -u user_name The MySQL username to use when connecting to the server.
