CMS for xml driven Flash website

[Zuko]

Hello guys,I d like to hear some recommendations about a situation i m facing..I have a few websites which are implemented in flash and are purely XML based.. (No db at all)(most of them are kinda like galleries.) XML files hold menu names , picture paths and everything.I m looking for a CMS or a tool or something that will make possible for the clients to update their data, pictures etc.. without writing any xml. I've stumbled across a few of them, Some require the use of a database and other just dont seem so user friendly.But anyway, i d like to hear a few recomendations. Would be better if someonne has actual experience in sth similar,so he knows whathe s talking about,, (Open-source first)thanx.
