Glad to hear it.
Outputting to xml would basically just be a script that loops through the tree output and wraps it in tags. The problem is I'm not sure what tags you would use, or what header info would be needed to make it a valid xml file.
Another option would be just plain html, again wrapping it in tags (maybe an unordered list, or a table).
Just dumping it to a file is probably easiest though
