UsersManager.getSitesAccessFromUser XML error

Hello,

Seems like trying out the API I have a problem with

UsersManager.getSitesAccessFromUser&userLogin=loginname&format=xml

It give me an error, while reading the XML feed.

I think the problem is due to that the nodes are numbered, like

<14>View</14>
<15>View</15>

Seems like it is not valid due to that.

Names cannot start with a number or punctuation character

I just created http://dev.piwik.org/trac/ticket/923
