[jQuery] Save reference to a element

[jQuery] Save reference to a element

I want a user to be able to reference (by clicking) an element on a web page and then save a reference to that element in a database for later retrieval.  What's the best way to do this?  (Assume that the html page will never change).  I could save some sort of path (body > div > div > ul > li > a...etc).  If so, is there a way to make an element spit out it's path, or at least some sort of unique identifier that can be used later to reference it.  Whatever I use to reference it must be able to be saved as a string so it can be stored away.
