Xml/search- fav system?

Hi

I found this… (xml search):p:

http://www.kirupa.com/web/xml/examples/searchbestof.htm

I see this working for my NW tourist app I am making for Uni. Region/ catogory.

Although I am wondering, I want to implement a priority/favourite system.

So then I can return stuff like top 5 locations in manchester for musuems.

And opinions?

I guess I would need a ranking node in the xml?

thanks
