export members as xml

I am looking to export my members as xml in the following format:

<members>
    <member>
        <username>foo</username>
        <screen_name>Mr. Bar</screen_name>
        <password type="md5">653132ffd94b986bf2bb806b3c67d190</password>
        <email>foobar@example.com</email>
    </member>

[...]
</members>

I cannot however, seem to find an option in the export menu in wordpress. Is there a plugin that will do this?
