Is there a XML editor of any type for the Nokia n810?

I am trying to replace my Palm apps. One of my most frequently used apps is Shadow Plan, which stores its data as XML. I also use Shadow Plan on my various desktop machines (this is true of most of my Palm apps), so I am not interested in using a different file format: I am looking for something to view and edit my Shadow Plan files on the n810.

So, does anyone know of any XML editors for the n810? Any recommendations?
