Persistent XML document?

[BigBang1112]

I've been working on Minigames title pack some time ago. Cool manialink minigames, to do fun stuff, etc. But, then I had a problem with saving system of these minigames which without it can make the work almost useless. One guy (not sure who, cuz fb real namez) then suggested an persistent XML idea. I've been asking for example, but with no result. So I need help from you.

Text above is just the story how I became with the thing I'm asking.
Can anyone show me example of persistent xml doc? Does persistent XmlDocument even work? It could extremly help a lot as I understand xmling, and you can be the savior of Minigames title pack! (sort of)

I know the thing that xmls are not really small data sometimes, so I can then use Integers and Texts and Reals etc. if a problem. But xml can make it more organized.

Thanks for any answer.

I would personally store data I need in keyed array, like Text[Text]. But if you really want an XML, you can save raw text with your XML data as persistent variable, but this requires creation of an XML text generator and a lot of other stuff going on.
